Mughal empire was only nominal in Delhi. From 1526 to 1707 A.D. Babur, Humayun, Akbar, Jehangir, Shahjahan and Aurangzeb followed all methods and tactics, diplomacy and war, friendship ‘ and alliances in order to keep entire India under their sovereignty.

Kings from different parts of India kept challenging them. In order to deal with the problems of the state Hindu Rajput kings had two options Surrender like other Rajput kings in front of Akbar, and become a part of Mughal organization and live a dependent life. Second option was to maintain their independence and defend the glory of their nation.

For following this policy they had to be prepared for fierce wars and leave the pleasures and family life. To protect their values, thoughts and respect of India some Rajput kings decided to’ fight against the Mughals. They gave tough challenge to the Mughal rulers with bravery. The prominent among them were the rulers of Mewir Ran. Sanga, Maharana Pratap, Rani Durgawati of Gond la, Maratha ruler Shivaji, and Sikh leader Govind Singh.

The Ruler of Mewar Maharana Pratap:
Rana Sanga gave stiff resistance in the plains of Khanna. Unfortunately Rana Sanga was defeated. After Rana Sanga Mughal power was resisted by Maharana Udai Singh. After Udai Singh’s death in 1572 A.D. his son Rana Pratap became the ruler of Mewar. He gave a tough challenge to Akbar till he lived.

Rana Pratap started organizing Mewar to give Mughals a fight. He organised feudal lords (Samants) and Bheels. He shifted his residence from Kumbhalgarh to Gogunde so that Akbar could not attack it easily. Through public relations he created awareness against Mughal power.

These efforts brought unity and the entire Mewar rose against the Mughal power. Akbar never liked the independence of Mewar. But Rana Pratap was not ready to accept the suzerainty, friendship or entering into a matrimonial alliance with Akbar. As a result war started between the two. Akbar’s armies conquered Gogunde. But Rana Pratap did not accept defeat. He carried on war against the Mughals and managed to win back many of the lost areas.

Rani Durgawati:
She was a valiant warrior of medieval history. When Akbar heard about the economic prosperity of the Kingdom of Gorha, he sent Asif Khan with a big army to attack on Gorha state for extending his empire. Rani Durgawati decided to fight than surrendering. She bravely fought against the forces of Asaf Khan but in the end she was wounded seriously. When she lost all hopes of winning the battle, she ended her own life.

Chhatrapati Shivaji:
The strongest opposition to the Mughal Empire, was given by Maratha’s under the leadership of Shivaji. Aurangzeb made several plans to trap Shivaji but was not successful. He sent the famous military commander Raja Jai Singh against Shivaji. But nothing happened in the favor of Aurangzeb. When Shivaji went to meet Aurangzeb with Raja Jai Singh, Aurangzeb treacherously imprisoned him. But, Shivaji managed to escape from there which made Aurangzeb extremely angry.

Write down the causes responsible for the decline of the Mughal Empire.
Answer:
Mughal Empire, the foundation of which was laid by Babur, its decline could be seen from the period of Aurangzeb. After the death of Aurangzeb in 1707 Mughal power declined rapidly. The chief causes of decline of this massive empire were as follows:

Aurangzeb’s Empire, his Policies and War:
Aurangzeb’s responsibility can be placed prominently as a chief of Mughal empires decline. His religious – orthodox policy and anti-Hindu policy was one of the chief cause. Due to his policy of oppression he made Jats, Rajputs, Maratha’s, Sikhs etc. as his enemies.

He oppressed the Hindus due to which he stopped getting the support of the Rajputs. Marathas and Jats gave severe blows to his empire, due to which Mughal Empire declined. To bring the kingdoms of the south under his subordination Aurangzeb fought for 25 years with the different states of South India, in which he had to face severe loss of men and money. These wars shook the foundation of the empire.

Excessive Taxes:
Mughal rulers imposed heavy taxes on the people for their pleasures and wars, paying which became impossible for the people. There were voices of revolt among the common man.

Vastness of Empire:
The vastness of Mughal Empire in and outside India also became a cause of decline of Mughal Empire. A vast Empire could have only been regulated through a centralized authority. Due to weak central authority the Mughal Empire also started breaking up. Akbar had saved the Empire by his diplomacy but his successors were not successful in this.

Revolts of Chieftains and Princes:
Revolts of Loyal Chieftains and Princes also helped in the decline of Mughal Empire. The revolts of royal leaders like Salem, Khusro, Shahjahan and /uirangzeb also gave a blow to the unity of the Empire.

War of Succession:
The war of succession for power also gave a deep wound to the Mughal Empire. There was no certain rule of succession in Muslim royal power. There were many claimants to tire throne due to which the successor was decided on the bayonet point. The war of succession between the sons of Jahangir and among the sons of Shahjahan for power aided the decline of Mughal Empire.

Moral Decline of Mughal Rulers:
Early Mughal rulers were loyal and virtuous towards their state. But the Mughal rulers after Jahangir were pleasure seeking and com-placement.

Religious Policy:
The religious policy of the Mughals was bias. Most of the rulers were staunch followers of Islam. They supported the spread and growth of Islam, whereas harmed other religions and other religion followers, due to which Mughal Empire could not get their support. Rise of Hindu Powers: The rise of new Hindu powers also played a role in the decline of Mughal Empire. Marathas, Jats, Sikhs, Rajputs etc.

reorganized themselves and rose against the Mughal empire which had struck Hindu culture. Continuous wars, autocratic rule decline of military power, moral decline of Amirs (Nobles), groupism and other reasons also aided the decline of Mughal Empire.

The prominent among them were potters, carpenters, weavers, plumbers, masons, artisans, bricks makers, bead-makers and sculptors. During the period, the priests must have occupied an important position and performed special duties. The remains found at Mohen – jo – daro point in this direction.

Besides these bureaucrats, military and government officials, intellectuals and traders and laborers also resided. The people of the Tarappan civilization had an artistic bend of mind. The people of the Harappan civilization were well versed in the art of hairstyles, indulged in ornaments and cosmetics. During this period people excelled in singing, music, dance etc. The statue of a dancing girl found during the excavation certifies the same.

Food habits of the period included both vegetarian and non-vegetarian food. Ornaments were made of copper, bronze, shells, ivory, clay beads, beads made of horn and bones, hair clips, finger rings, bangles, necklace, amulets, bracelet, anklets, earrings were worn as ornaments.

They were also fond of hunting. From the remains found at Mohen-jo-daro a Yogi’s image on one of the seal (resembling Pashupatinath – Shiva) Rock Lin – gas (resembling Shiv Linga) can form an idea of the religious beliefs of the people. Besides these evidences of worship of snake, trees, the sun and water have also been found from excavation.

Economic Life in the Indus Civilization:
The economy I of this period was well developed. Agriculture was the main occupation. Besides agriculture, animal rearing, industry, internal and external trade, statue making industry, bricks industry, sculpture etc. were the chief industries. Indus people had trade relations.

• Linear scale.

Question 4.
What is represented by a physical map?
Answer:
A physical map shows the physical features of the region, for example, hills, mountains, rivers, plain, plateaus etc.

MP Board Class 9th Social Science Chapter 8 Short Answer Type Questions

Question 1.
Differentiate between a sketch map and a map.
Answer:
There are certain points which are necessary in a geographical map called elements of a map. Without these elements (direction, title and sub – title and conventional signs) a map is incomplete and we call it a Sketch map. A map possesses all these elements.

Question 2.
What is the importance of scale in a map?
Answer:
map cannot be drawn without a scale. It is not possible to. draw a map of the whole earth surface on a paper because finding a huge paper is difficult. To draw a suitable map we use scale, according to which some topographic features are drawn on a plane paper in a map. There is a ratio between the distance of two points on a map and the distance between the corresponding points on the actual ground. This ratio is known as scale.

Question 3.
What is Representative Fraction?
Answer:
Scale of a map may also be indicated by a fraction called the Representative Fraction (R,F.) in which numerator is 1. The numerator represents the distance on the map while the denominator indicates the actual distances on the ground.

For example, the R.F. of a map indicates as 1/1,000,000 or 1 : 100,000. This means one unit of distance on the map is equal to 1,00,000 units on the ground. The unit may be measure of length. Thus the R.F. is independent of any particular unit of measurement. If the R.F. of map is 1:100,000 it means that the scale of a map is 1 cm to 100,000 cm or 1 km.

Question 4.
Explain statement scale.
Answer:
Scale presented in the form of a statement like 1 cm to 10 km. is called statement scale. This scale shows that 1 cm represents a distance of 10 km. on the ground.

Question 5.
What is the utility of interpretation of a map?
Answer:
We can collect sufficient information of an area from its map by interpretation. We can know about the physical features present in the area depicted in the map. For example, water bodies, hills etc. We can also know about the means of transport – like rail routes, air-routes, roads etc. that join the given area with other places.

Question 6.
What are contour lines?
Answer:
1. Contour Lines. They are imaginary lines drawn on a map. They join places having the same elevation or height above the sea level. These lines are best suited to depict the relief feature – the delineation of hills and plains and distinguishing of high grounds and low grounds.

If so many contour lines are drawn, say showing areas with heights of 400, 600, 800, 1000 feet above sea level, then it is possible to know the shape of the land. But the contour lines have some defects also. They give the height above the sea-level but not the actual height. Moreover, they do not help us in determining certain other features of the geographical data. In this regard their scope is limited.

Question 1.
What is the importance of a scale’?
Answer:
Scale is the most important item in the study of maps:

• With the help of scale, we can represent large areas in a reduced shape and size.
• Without a scale, a map is simply a diagram or sketch. A , map is meaningless without scale.
• We can measure the distance between two paints on the map without going to the field.
• A map can be reduced or enlarged with the help of a scale.

Question 2.
What do you mean by conventional signs? Show the following by conventional signs.

1. Temple,
2. Metalled road,
3. Post Office
4. Broad guage rail line
5. Settlement

Answer:
The topographical features like mountains, plateau, plains, rivers, and man – made structures like settlements, railway path, roads etc. are shown with the help of pictures in the map. They are called conventional signs.

Question 3.
Write short note on ’Layer co-louring’
Answer:
This is a very common method of showing distribution of relief over a wide area. Atlases and wall maps follow this method almost universally. The color scheme adopted in showing the relief or elevation is almost uniformly followed everywhere. The sea is colored blue. Usually deep blue indicated deep sea and light blue stands for shallow sea. Low lying areas are shown in deep f green and as the land rises in elevation, light green, light brown, dark brown, crimson red and white are used in the ascending order.

Question 4.
What are distribution maps? Name its types. Give examples.
Answer:
Distribution maps show the distribution of an element in the form of value, intensity or density. These are of two types – Qualitative and Quantitative. Vegetation maps and Soils maps are Qualitative maps, whereas population maps are Quantitative maps. Population distribution is shown with the help of dots. Each dot represents a specific number of persons.

• Ridge – Contours are elongated circles.
• Valley – Contours are inverted V’ shaped.

MP Board Class 9th Social Science Chapter 8 Long Answer Type Questions

Question 1.
In what ways is the scale represented on a map?
Answer:
There are different methods of representing scale on a map.

1. By a Statement:
The scale, in this method is expressed by a statement. This means that the scale is stated in words such as 1 centimeter to 1 kilometer. This scale would be interpreted as one centimeter on the map corresponds to one kilometer on the surface of the earth. The reason is that this indication of scale would be understood by only those who are familiar with particular unit of measurement.

2. By a Representative Fraction (R.F.):
Scale of a map may also be indicated by a fraction called the Representative Fraction – (R.F.) in which numerator is 1. The numerator represents the distance on the map while the denominator indicated the actual distance on the ground.

For example, the R.F. of a map indicates as 1/1,00,000 or 1 : 100,000. This means one unit of distance on the map is equal to 100,000 units on the ground. Hie unit may be measured of length. Thus the R.F. is independent of any particular unit of measurement. If the R.F. of map is 1 : 100,000 it means that the scale of a map is 1 cm to 100,000 cm or 1 km.

3. By Linear Scale:
The linear scale is a line conveniently divided and sub-divided so that the distance on the map can be directly measured and read out from the map in term of distances on the ground in kilometers. Linear scales are used to measure actual distances between different places on the map.

Question 2.
What are conventional signs? Draw some important conventional signs.
Answer:
Conventional Symbols (Signs) of towns, villages, buildings, railway lines, roads, trees etc. are big features. It is extremely difficult to draw on a map the actual shape and size of these features. Therefore, we use various symbols to show them on the map. All the countries use the same symbol for a particular feature.

These symbols are recognized all the world over and are called Conventional Symbols or Conventional Signs. These symbols are very useful in understanding the features of the lands shown on the map. Roads, towns, buildings, etc. are shown in red color. Black lines show railways. Rivers, canals, tanks, lakes and other water bodies are shown is blue color.

Question 3.
Write in detail on ‘Representation of Relief Features.’
Answer:
The surface of the earth is not same everywhere. It has various land forms like mountains, plateau, plains, rivers, valleys etc. The three – dimensional presentation of various relief features is known as Representation-of Relief Features. The height or a depth of a place is measured from the sea level. The imaginary lines joining places having the same elevation above or below the sea level are called contour lines and measured from the mean sea level.

This level is known as Datum Plane. The height at this plane is considered as zero and with reference to this base line the height of the place is measured. In small scale maps like wall maps and atlas maps, relief features are indicated by a scheme of graded colors. Each latitudinal zone is indicated by a particular color. Usually low lands are indicated by shades of green. Higher elevations are represented by shades of yellow, brown, red and violet.

Snow capped peaks are shown as white or left uncolored. Heights are indicated in meters or feet. Depth of the.sea is shown by varying shades of blue. Darker shades indicate greater depth in the Ocean. Means the highest part (mountains) or the deepest part (Oceans) should be indicated by the darker shades and less deeper parts is represented by lighter shades. In this way relief features like mountains, plateau and plains are represented.

On large scale maps, like topographic maps relief features are shown by contour lines. In the maps places of same height above sea level are shown by contour lines. Contour lines are based on a detailed survey of heights of several places in an area. The heights of each one of these places is marked on a map and contour lines are drawn by interpolation. These lines are drawn at definite intervals such as 20, 50 or 100 meters.

It should always be in numbers ending with zero. Spacing of contours gives an idea of the slope or gradient. If contour lines are closer, it indicates a steep slope and gentle slope is indicated when on tours are widely spaced. Contour diagrams of some of the mator land forms are given in the figure which will help you understanding the slopes. The contour diagrams of slopes, hill, plateau, escarpment, cliff, river valley and lake are different from each other.

Due to the population growth many problems are coming up in our country. Among many problems, there are given below:

• Poverty
• Unemployment
• Decline of standard of living

Question 2.
Why is the rate of sex – ratio declining in India? Give reasons.
Answer:
The rate of sex – ratio is declining in India due to the following reasons –

• Literacy is low among females.
• High maternal mortality rate.
• Desire of male child in a male dominating society.
• Increasing female foeticide.
• Neglecting girl child and considering girl child as a liability.
• Dowry system in the society causes female foeticide and encourage females towards suicide.

Question 3.

Answer:
Following National Population Policy 2000, National Commission on Population has been established. The Prime Minister is the President of this commission. Chief ministers of all States and Union Territories, administrators and ministers, in charge of all related departments and central ministers, renowned demographers and the representatives of public health and professional organizations and non – government organization are its members.

Following the National Population Policy 2000, state level population commissions like the National level population commission have also been formed. The chief ministers of the respective states are their .presidents.

Question 4.
What do you mean by sex – ratio? Explain its distribution in the country.
Answer:
Sex – ratio means number of females per thousand males. According to census 2001 the sex – ratio for the country was 933 (there are 933 females per thousand males) meaning that the number of females is less than number of males. This means that the sex – ratio in India is adverse. When the number of females is more than males the sex – ratio is said to be favorable.

There are wide regional disparities in sex – ratio in India. When we will go through the map of distribution of male-female ratio we find that Kerala records favorable sex – ratio (1058).whereas in Chandigarh it is adverse (773)
The distribution of male – female ratio are as under:

MP Board Class 9th Social Science Chapter 7 Long Answer Type Questions

Question 1.
Give the main causes of population growth in India and the measures being taken to control it.
Answer:
The main causes of population growth in India are:

1. Birth – rate and death – rate:
During 1911 to 1921 birth – rale and death – rate were 48.1 and 47.2 respectively, meaning that both were quite high. From 1921 to 1951 though birth – rate decreased slowly but, death rate decreased rapidly. Between 1991 and 2001 difference between the two increased to 17.4 resulting in continuous growth of population. The cause of decline in death – rate was increase in health facilities and adequacy of facilities of livelihood.

2. Increase in Life Expectancy:
The difference between birth – rate and death-rate is called natural growth rate. The average age of life is known as life expectancy. In our country, life expectancy (average age) was 50 years in 1921 which increased to 62 years in 1991. Hence due to longevity population kept on increasing.

3. Lack of Education:
In education gives birth to superstition.. Most of the uneducated people believe that children are gift of God. Believing this they keep on begetting children and hence population also increases. Desire for son is also responsible for many children in one family. The lower class hesitate from adopting family welfare programmer.

4. Other Causes:
Poverty, lack of means of entertainment, low standard of living, child marriage and migration etc. are among the other causes of population growth. Due to population growth many problems are coming up in our country, such as poverty, unemployment, decline of standard of living, hunger, increasing crimes, housing problem, transport problems, lack of medical facilities and increasing pollution etc.

5. Measures to Control Population Growth:
If the population growth is not checked immediately, flow of development will be hampered in the future. Following measures are essential to control the growth of population.

• Family welfare programmer should be accepted.
• Spread of education especially women education should be increased.
• Child marriage should be prevented.
• Standard of living should be improved.
• Social security should be rapidly extended.

Question 2.
Explain with examples the factors affecting the density of population in India.
Answer:
The factors affecting the density of population in India are –

1. Physical factors.
2. Socioeconomic and cultural factors.

1. Physical Factors:
Terrain, climate, soil and minerals are main physical factors. Terrain affects distribution of population the most. On one hand, dense population is found in the plains of Ganga – Yamuna and coastal areas, whereas on the other hand in the hilly state of Arunachal Pradesh density of population is the lowest. Climatic condition also influences density and distribution of population.

Suitable climate is helpful to the health and efficiency of man. The dry deserts of western Rajastan and Arunachal Pradesh are sparsely population due to bad climate. Fertile soil is ideal for agricultrue. The agriculture crops are the fundamental bases of livelihood and sustenance.

Therefore, population clusters around the fertile plains of rivers. Availability of minerals and industrial development based on them has attracted population in the mineral areas of Chottanagpur Plateau. Thus population has become very dense in Chottanagpur Plateau region.

2. Socioeconomic and Cultural Factors:
Socioeconomic and cultural factors also play important role in the distribution and density of population. The cultural, social, historical and political factors have together raised the size and density of Do population in the Mumbai-Pune industrial area.

Many years from today Mumbai area was non – significant, but after the advent of Europeans its importance kept increasing and gradually it turned into commercial and industrial center, as a result its population increased. Today a large group of people go to stay from one place to another and from one country to another. This is called population migration. Population migration also affects a country’s population growth.

Question 3.
On the basis of population density, in how many parts India can be divided?
Answer:
India can be divided in four parts on the basis of density.
1. High Density Areas:
If we look at the population density map of India, we find that more than 501 persons reside in per square km. area in Uttar Pradesh, Bihar, West Bengal and Kerala. The fertile land and availability of water provide enough facilities of sustenance. In these areas urbanization and industrialization have provided people with sufficient employment opportunities and services.

2, Medium Density Areas:
These include areas having population density of 251 to 500 persons per sq. km. Andhra Pradesh, Assam, Goa, Maharashtra, Tamilnadu, Jharkhand, Punjab, Haryana, Tripura, Dadra and Nagar Haveli fall under this category. Developed agriculture, availability of minerals and industrial development are some of the reasons for high (medium) population density in these areas.

3. Areas of Normal Density:
These include all those states which have population density ranging from 101 to 250 persons per sq. km. The States included in this category are M.P., Rajasthan, Orissa, Chhattisgarh, Uttaranchal, Meghalaya, Manipur and Nagaland. These are hilly and dissected semi arid, forest covered regions. Here the means of livelihood are quite limited.

4. Low Density Areas:
These include Jammu and Kashmir, Arunachal Pradesh, Mizoram, Sikkim and Andaman and Nicobar Islands. Hilly areas, lack of transport facilities, under – development of agriculture and industries are the responsible factors for low density. The means of livelihood are very limited here. In Arunachal Pradesh, density of population is as low as 13 persons per sq. km.

The Status of Growth in Literacy Rate in India:
Literacy rate has increased in last hundred years. It is evident from the table of status.’of literacy’ in India given on the next page that in the. beginning of the century in 1911 the literacy rate was about .6%. After Independence in’ 1951 it’has increased to 18.13%. It has increased . from 52.21% in 1991 to 65.38% in 2001 in female Literacy rate was 1.1% in 1911 which has increased to 54.16% in 2001. It is out come of the policy of Central Government aiming at providing free primary education to all.

Disparities in Literacy Rates:
There are wide regional dis – parities in literacy rate. See the state – wise distribution of literacy in the map. It varies from 47.5% in Bihar to 90.9 in Kerala. Kerala is closely followed by Lakshadweep (87.5 percent) and Mizoram (88.4 per cent). Bihar ranks last in literacy among the states and union territories of India.

Male – female differentials are also wide. Only 54.16 per cent of the females are literate as against 75.85 per cent of males. There is much difference in the literacy rate of rural and urban population. In 2001 the literacy rate in urban areas was 79.9 per cent, whereas in rural areas it was only 58.7 per cent.

MP Board Class 9th Social Science Chapter 7 Short Answer Type Questions

Question 1.
What is density of population? How can density of population be calculated?
Answer:
Density of population is the number of people living per square kilometer of area. It represents the land man ratio. It can be calculated by dividing the total population of a region or country or state by its total area. It is expressed as the number of persons per square kilometer as 180 persons per square kilometer.

The distribution of population of India is extremely uneven. The average density for the country as a whole as per the census 1991 in India is 267 persons per sq. km. The density of population in India can be calculated by dividing total population with total area. Thus density of population = Total population s ÷ Total area.

Question 2.
Describe the areas m normal density.
Answer:
These include all the e states which have population density ranging from 101 to 250 persons per sq. km. The states included in this category are M.P. Rajastan, Orissa, Chhattisgarh, Uttaranchal, Meghalaya, Manipur, and Nagaland.

Question 3.

Answer:
Following measures can be taken to control the growth of population:

• Family welfare programmer should be accepted.
• Spread of education especially women education should be increased.
• Child marriage should be prevented.
• Standard of living should be improved.
• Social security should b’e rapidly extended.

Question 4.

• Long term objective – To achieve the target of stable population for sustainable economic development till 2045.

MP Board Class 9th Social Science Chapter 7 Long Answer Type Questions

Question 1.
Define birth and death rate. Explain growth rate. Also make a table to show growth rate in India (1901-2001).
Answer:

1. The birth – rate is calculated in terms of number of live birth per thousand population per year.
2. The death – rate is known as number of deaths per thousand population per year in a given area.
3. The difference between these two is called the natural growth rate per year.

Growth rate in India (1901-2001):

The growth rate of a population may be positive or negative. Positive growth rate means growth in the number of people living in an area, whereas negative growth means the number of people living in that area declines. Find out the population growth rate m India from the table given above and see whenever the growth was negative.

Question 2.
What are the main features of population situation in India?
Answer:
The main features of India’s population can be summarized as below:

1. Size of India’s Population:
India is the second largest populated country in the world, after China. Population of India has been constantly rising since 1921. The following figures indicate the size, of India’s population.
Population of India

It will be seen from the above table that in just 34 years after independence another India was added while the territorial limit of the country remained unchanged. It is estimated that if we grow with this number, we will be more than 100 crore mark at the end of this century.

2. Second Largest Populated Country:
India has 2.4 per cent of the total land area of the world, India caters to the needs of 15% of the total world population. This means every seventh person in the world is an Indian.

3. Population Increasing at a Fast Rate:
It is not the overall absolute size of population which is the cause of concern, equally important is the fact that India’s population has been rising at a relatively very fast rate. It has gone up by a little over 2.0 per cent annum during the period 1951 to 1991 and about 2.1% presently.

4. Density of Population:
The density of population of India in 1961 was 216 persons per.sq. km. It rose to 267 in 1991. Thus the land man has been declining fast which indicates that the land will fall short for the in habitation of mankind of the population grow in this rate.

5. Uneven Distribution of Population:
The population is unevenly distributed. The northern plains, coastal plains and some river valley in lower Himalayas are densely populated while other areas of scanty rainfall or desert plateau and mountainous areas are sparsely populated. Thus there are areas which have great population pressure while other rare less inhabited.

Question 6.
Differentiate between Evergreen and Deciduous Forest.
Answer:
Differences between Evergreen Forests and Deciduous Forest.

Evergreen Forests:

1. The forests having trees which remain green throughout the year. This means that seasonal shed – ding of leaves does not take place.
2. Shedding of leaves and growth of new leaves is continuous process and it goes side by side throughout the year.
3. Ever green forests are found mainly in equatorial regions where rainfall is very heavy and where there is no dry season.
4. Trees like eucalyptus, oak, wattle, Mahagony, Man – grove and Rosewood are common in these forests.

Deciduous Forests:

1. The forests consisting of trees which loose their leaves at some season of the year are called deciduous forests.
2. Tropical deciduous forests are found in sub – tropical regions with a distinct dry season such as Monsoon regions of Asia, parts of central America, Brazil and North Australia.
3. These forests have fewer than tropical evergreen forests.
4. In case of Monsoon forests, the trees shed their leaves during the. hot season. Teak, Oak, Elm and Beach are important timber products.

Question 7.
Explain the chief characteristics of tropical moist ever green forests.
Answer:
The chief characteristics of tropical moist evergreen forests are:

1. These forests thrive in areas having annual rainfall above 300 cm and dry season is short.
2. These forests are very dense, length of the trees in 60 m or more.
3. Layers of different height can be seen in these forests. Shrubs, climbers and creepers are found under tall trees.
4. Grass is generally not found in this region.
5. The wood of these trees are hard and heavy,
6. These forests do not have a distinct season of shedding of leaves, so these forests appear to be evergreen.
7. The main trees found here are rubber, mahogany, cinchona, bamboo and palm.

Question 8.
Describe how forests are useful to man?
Answer:
Forest is a natural wealth. It has various uses for humans. Forests contribute in the economic development of the country by functioning in two ways production and conservation. we have two types of benefits from the forests – Direct benefit and Indirect benefit.

Direct Benefits:
They give us timber, fuel wood, fodder, raw material for small and cottage industries, valuable minor products (fruits, flower, grass and leaves) and raw material for medicines. It is a main source of livelihood for many people.

Indirect Benefits:

1. Indirect benefits of forests are more important than direct benefits. They are the essential part of our nature and culture. They increase human values, provide spiritual strength and are the habitat of entertainment ancL recreation.
2. Forests affect the temperature of the air control the speed of wind and control the climate by rainfall.
3. Forests control floods and the soil erosion by controlling the flow of rivers.
4. Forests increase the fertility of soil by adding humus formed due to the decomposition of the leaves and branches of the trees.
5. Forests are the natural habitat of birds and animals.
6. Forests are the symbol of natural beauty.
7. Forests are the source of natural balance.

Question 9.

They increase human values, provide spiritual strength and are the habitat of entertainment and recreation. Forests affect the temperature of the air. They control the speed of wind. They also control the climate by rainfall. Forests control floods and soil erosion by controlling the flow of rivers. They increase the fertility of soil by adding humus.

MP Board Class 9th Social Science Chapter 6 Long Answer Type Questions

Question 1.
Describe various types of vegetation in India.
Answer:
1. Tropical Evergreen Forests:
These are of two types.

(A) Tropical wet evergreen forests:
The forests thrive in areas having annual rainfall above 300 cm. and dry season is short. These forests are very dense, length of the trees is 60 m or more. Layers of different height can be seen in these forests. Shrubs, climbers and creepers are found under tall trees.

Grass is generally not found in this region. The wood of these trees is hard and heavy’. These forests do not have a distinct season of shedding of leaves, so these forests appear to be evergreen. The main trees found here are Rubber, Mahogony, Cinchona, Bamboo and Palm.

(B) Tropical wet semi-evergreen forests:
These forests are restricted to the areas where annual rainfall is between 200 to 300 cm. So these evergreen forests are found in the Central parts of temperate moist deciduous forests. These forests are found in Mehgalaya, Mizoram and Andaman and Nicobar Islands. They are less dense than wet evergreen forests. The important plants here are Rosewood, Ebony’, Telsur, Champa, Jun, Gurjan, Ice-wood and Laurel.

2. Tropical Deciduous Forests:
This is the largest belt of India, these forests are also known as Monsoon forests. They cover 39% of the total forest area. (See the distribution of these forests in the Vegetation Map) On the basis of availability of water these forests are classified into two parts Moist deciduous forests and Dry deciduous forests.

Moist deciduous forests are found in the area of 100 to 200 cm. rainfall in India, North-east states, foot – hills of Himalayas, Jharkhand, Western Orissa, Chhattisgarh and the eastern slopes of Western Ghats. Teak is the main species of these forests. Other trees are Bamboo, Sal, Shesham, Chandan, Khair, Kusum, Ar-jun and Mulbery.

Trees of these forests shed their leaves during the dry season for 6 to 8 weeks. To fulfill the demand of wood these forests have been exploited and cleared for cultivation. The areas with 70 to 100 cm. rainfall have Dry deciduous forests. The main areas of these forests are Peninsular Plateau, Uttar Pradesh and Bihar. Main trees are Teak, Sal, Pee-pal, Neem and Mango.

3. Mountainous Forests:
(A) Peninsular mountain forests:

• On the high altitudes of Peninsular Plateau open wavy grasslands are found with the shrubs or undeveloped forests.
• Dense vegetation is found under tall trees in these forests. Heterotrophic plants, mosses and plants with small leaves are found in these areas.
•  Maglonia, Laurel, Elm are the common trees whereas Cinchona and Eucalyptus are brought from foreign countries and planted here.
• There forests are found in Nilgiri, Palni, Annamalai, Western Ghats, Mahabaleshwar and Satpura and Maikal ranges.

(B) Mountainous forests of Himalayan Ranges:
In Himalayan mountainous region due to increasing altitude and decreasing temperature a difference in natural vegetation is seen. In Shivalik ranges, at an altitude of 1000 meters in the foothill region, Bhabar and Tarai tropical deciduous forests are found.

It is then succeeded by temperate moist evergreen forests between 1000 and 20000 meters. These are the dense forests with tall trees. Oak and Chestnut are found on eastern Himalayas and Pine on western Himalayas.

At an altitude of 2000 to 3000 meters forests of Deodar, Silver fur, and Spruce are sparsely distributed. Sal is mainly found at low altitudes. On the slopes of the high altitude mountains, where temperatures are low and rainfall is less than 100 cm dry temperate vegetation similar to that of Mediterranean vegetation, is found. Olive,. Babool and hard Savanna grass is found with Oak and Deodar trees.

Alpine vegetation is found between the altitude of 3000 to 4000 meters. These are less dense forests and the height of the trees decreases towards Snowline. At higher altitudes alpine pastures are found. Silver fur, Juniper, Birch and Pine are the main species of these forests.

4. Mangrove Forests or Tidal Forests:
Mangrove or Tidal vegetation is found on the coastal areas of India where the tides occur. Mangrove is a type of vegetation with submerged roots. This vegetation is found in the delta region of the Ganga, Bhahmaputra, Mahanadi, Godavari, Krishna and Kaveri rivers. Sundari is a well – known mangrove tree found in the delta region of Ganga-Bhrahmaputra. Coconut, Palm and Agar trees are also found in this region.

Wild Life of Mangrove Forests:
Royal Bengal Tiger is famous in these forests. Tortoise, Crocodile, Alligators and different types of snake are found here.

5.  Tropical Thorny Forests:
The areas with less than 70 cm annual rainfall have thorny forests and shrubs. This type of vegetation is found in the northwestern parts of the Country. It includes Gujarat, Rajasthan, Madhya Pradesh, Uttar Pradesh and semi-arid regions of Haryana. Date, Palms, Babul, Cactus is the main vegetation here. These plants have long roots spread in a radial pattern in search of water.’ Leaves are small to reduce evaporation.

Question 2.
Why is conservation of forest resources necessary? Give examples of different measures for their conservation.
Answer:
Forest conservation is necessary because our life is dependent on it. Forests provide us food. They help in the maintenance of ecosystem. They give oxygen which is necessary for survival of our life. Forests contribute in the economic development of the country. Different measures for their conservation.

Forest is a national wealth. Looking to the problems originated due to decreasing forest resources, their conservation is very necessary. Human needs are unlimited whereas the natural resources are limited. So, efforts for afforestation has been encouraged by the government.

Question 1.
Write a short note on conservation of wild – life
Answer:
The wild-life of a country is a part of its heritage. Every effort should therefore be made to protect – and preserve the wild life. Today there are man – endangered species of wild – life birds and animals. The Indian bustard of Rajasthan and Malwa, number of lions and tigers are some of the endangered species.

In order to conserve this resource, government of India has been taking time-to-time suitable measure, to maintain this great biological diversity of our land. Periodic census undertaken to find out the latest position and trends in this regard. The project tiger has been a great success. Now there are 16 tiger reserves in various parts of the country.

Likewise Rhino Project is being implemented in Assam, The Biosphere Reserves have been set up in the Nilgiries. It consists of 5500 km and is spread at the trijunction of Karnataka, Tamilnadu and Kerala. The other bio – reserves have been set up as Nanda Devi in U.P., Noktek in Meghalaya, Andaman and Great Nicobar etc. The country has 63 national parks, 358 wild life sanctuaries and 35 zoological gardens covering 130000 km² of area.

Question 2.
Describe the factors affecting vegetation.
Answer:
The geographical factors or elements affect the development of vegetation of a particular area. The important elements are rainfall, temperature, humidity, soil, altitude and geological structure.

1. Earth Surface:
It includes relief features and nature of soil.

Land:
Land affects vegetation directly and indirectly. Mountains, Plateaus and Plains do not have same type of vegetation. Plain surface is useful for agriculture. Forests and grasslands are found on rugged and uneven surface, which are the habitat of wild – life.

Soil:
Different type of soil is found on different places which is a base for different type of Vegetation. Mangrove forests are found in delta region of rivers. Whereas conical forests on the slope of high mountains plain areas are favorable for agriculture – and deciduous forests are found on plateau region normally.

2. Climate:
Temperature Favorable temperature is required for the germination, growth and reproduction of the plants. Variety of plants grow in the tropical zone because of high temperatures and humidity. Increase in temperature by 6°C to 9°C results in the stunted of the plants. Temperatures are low on high mountains therefore the growth period of the vegetation is short

Sunlight:
Duration of sunlight at any place depends on latitude altitude from sea level and the season. Plants grow rapidly in summer season because in Summers the duration of day light is more. As the Southern slopes of the Himalaya mountainous regions receives more sunlight as compare to northern slopes, dense vegetation is found here.

Rainfall:
In the areas of heavy rainfall the forests are very dense with tall trees. In the areas of low rainfall dwarf trees, grasses and shrubs are found sparsely. In desert areas plants have long roots. To prevent the loss of moisture due to transpiration some plants have wax-coated and thorny leaves. Vegetation of Thar desert is thorny due to scanty water.

MP Board Class 9th Social Science Chapter 5 Short Answer Type Questions

Question 1.
How do the relief features of India affect the climate?
Answer:
The relief features of India influence the temperatures as well as the rainfall. The Himalayas on the northern boundary of the country extending from east to west protect India from cold breeze coming from the North in winter season. They intercept the moisture bearing monsoon winds and help in precipitation.

Question 2.
Why is the climate of northern India uneven?
Answer:
The climate of northern India is of Continental type. Distance from the sea and temperate climate effect its climate. Hence the climate here is uneven.

Question 3.
Why does the Tamilnadu coast receive rainfall in the winter season?
Answer:
Tamilnadu coast receives most of the rainfall by they retreating monsoons. These winds blow in the months of October and November from the land to sea through north – east direction. When they cross over Bay of Bengal they pick up moisture and cause rainfall in Tamilnadu.

Question 4.
Which are the high rainfall areas of India?
Answer:
Bihar, Jharkhand, Orissa, Eastern Uttar Pradesh, Tamilnadu and West Bengal are the highland rainfall areas of India.

Question 5.
Why is Indian agriculture called a gamble of monsoon?
Answer:
In India agriculture depends on monsoon which is most uncertain. Sometimes it arrives on time and it rains in adequate amount. But sometimes it is late and the amount of rainfall is less. It adversely affects the agriculture. That is why Indian agriculture is said to be a gamble of monsoon.

Question 6.
How does climate affect the health?
Answer:
It has been seen that sultry hot weather is followed by widespread rains which give rise to many diseases. Water is stored in the pots and ponds, which becomes the birthplace of mosquitoes and spread diseases. Thus, climate affects our health too.

Question 7.
How do monsoon winds originate?
Answer:
Monsoon winds are related to weather because they blow from land to sea for six months and from sea to land for next six months. There are several concepts of the origin of monsoon but the thermal concept is important. According to this concept, monsoon winds are in fact land and sea breezes on a large scale.

By differential heating of the land and the sea winds blow from sea to land in the daytime and from land to ,sea in the night. Similarly in summer season winds blow’ from high pressure system on sea to low pressure system on lands. During winters, a complete reversal takes place with high pressure on the land and the low pressure over the sea. At this time winds start blowing from land to sea. This is called monsoon.

MP Board Class 9th Social Science Chapter 5 Long Answer Type Questions

Question 1.
Explain the factors influencing the Indian Climate.
Answer:
The factors influencing Indian climate are:
1. Latitude:
India is situated in the northern hemisphere in the south of Asia continent. Tropic of cancer passes through the center of the country. Due to this specific location, its southern part has tropical climate and northern part has continental type of climate.

2. Distance from the sea:
The effect of the distance from the sea is very clearly seen on the distribution of temperature of India. That is northern plains have continental type of climate.

3. Relief features:
Relief features of the country influence the temperatures as well as the rainfall. The Himalayas on the northern boundary of the country extending from east to west protects India from cold breeze coming from the north in winter season. They intercept the moisture bearing monsoon winds and help in precipitation.

4. Distribution of water and land:
India is a part of Asia continent. During summers the north – western plains of India gets more heated and center of low pressure is established here. This low – pressure area attracts the winds coming from the Indian Ocean. During winters this area becomes more colder and center of high pressure develops here and wind starts blowing from land to sea. These winds influence the climate of India. Rainfall occurs due to the winds coming from the sea.

5. Jet streams blowing in the upper atmosphere:
A westerly jet stream blows above northern India in winter season but in rainy season it moves northwards above Tibetan plateau. Easterly jet stream develops at about 15°N latitude. Nature of these jet streams is responsible for summer monsoon. Shifting of jet streams towards north and south is the cause of uncertainty and irregularity of south-west monsoon in India.

6. Monsoon winds:
In India monsoon winds blow in summer from sea to landmass and in winter season from landmass to sea. This change in monsoon winds changes the weather and seasons in India.

Question 2.
Explain the main characteristics of the monsoon and describe the different seasons.
Answer:
Main characteristics of monsoon –

1. Monsoon winds are seasonal winds. They blow according to season.
2. Seasonal winds blowing in summer season are called summer monsoon and winds blowing in winter season arc called winter monsoon.
3. Due to the peninsular shape of India summer monsoon winds divide into two parts. The Arabian Sea Monsoon and the Bay of Bengal Monsoon.
4. In summer season these winds blow from south – west to north – east and in winters from north – east to south – west in India.
5. These winds are hot and humid in summer season as they blow from sea to land whereas in winters they are cold and dry because they blow from land to sea.
6. Rainfall in India is due to monsoon winds. Maximum amount of rainfall is received from south – west monsoon winds.
7. Time of monsoon and amount of rainfall vary.

Different Seasons Of India:
Four main seasons are:

1. Cold Weather Season
2. Hot Weather Season
3. Advancing Monsoon Season
4. Retreating Monsoon Season

1. Cold Weather Season:
December to February. The cold weather persists from December to February throughout India. January is the coldest month. Temperature varies from 10°C to 25°C. Temperature is between 10°C to 15°C in the northern plains and 25°C in the southern parts of the country. There is high pressure the northern plains due to the cold climatic conditions. The cold dry winds blow from the high pressure towards the low pressure equatorial regions.

These winds are north – westerly in the Ganga Plains and north- easterly over the Bay of Bengal. Culy two parts of the country receive rain in this season. First is the north – west part of India which receives rainfall from the Mediterranean cyclones. Second is tire Coast of Tamilnadu which gets rainfall in winter because of the north – east winds which blow over the Bay of Bengal. But in other parts of the country, the weather is pleasant with clear skies and bright sun – shine.

2. Hot Weather Season:
March to May. During this period there is a rapid shift of the belt of heat from south to north. In March, April and May the highest day temperatures occur in the Deccan Plateau (38°C), Gujarat (43°C) and North-West of India (48°C) respectively.

In May the rising temperature leads to low pressure in a wider area from the Thar Desert to Chhotanagpur. Because of this low pressure the moisture – laden winds from the Arabian Sea are attracted towards this area and consequently there is (about 158 ems) rainfall in the Rajmahal and Chhotanagpur Hills lying between the Satpuras and the Vindhyas.

Kerala and Western Ghats also experience the pre – monsoons showers. Assam and Bengal also receive some rainfall by means of evening thunderstorms. Bid the north – west areas remains dry, and hot winds, called the too, engulf the whole areas. Sometimes dust storms in Punjab, Haryan and U.P. are followed by light rain and cool breeze.

3. Advancing Monsoon season:
This season runs from June to September. During these mouths Me south – west monsoon winds blow northwards in two branches from the Arabian Sea and the Bay of Bengal. They make rainfall almost in the whole of northern India.

These winds blow from the oceanic high pressure areas towards the low pressure areas of land and make a heavy rainfall. The Arabian Sea branch causes heavy rainfall exceeding 300 ems along the coastal areas of the Western Ghats but this rainfall decreases as the monsoons go further.

As such Kutch receives less than 40 cm of rainfall. The Bay of Bengal branch causes heavy rainfall in the hills of Assam. Cherrapunji receives more than 1,000 cm of rainfall annually. As the monsoon winds take a turn from east to west because of the Himalayas, the rain goes on decreasing. As such when Kolkata gets, a rainfall of 119 cm Allahabad gets 76 cm due to the uncertainty and uneven distribution of rainfall,, floods and droughts are common during this season.

4. Retreating Monsoon Season:
This seasons is in October and November. In this season the monsoons start to retreat back. Passing over from Bay of Bengal they strike on the coast of Tamilnadu and give sufficient rainfall. This rainfall is not certain and equally distributed.

Question 3.
Show the distribution of rainfall in the Map of India and name the different areas.
Answer:
Areas of Very High Rainfall. Assam, the Ganga Delta, the Western Ghats and the Western Coastal Regions and the north mountainous regions (the Himalayas) receive heavy rainfall of 200 cm and above annually.

Areas of High Rainfall:
Areas which get annual rainfall between 100 cm to 200 cm roughly come under this group. Madhya Pradesh, Onssa, Chhota Nagpur, Western Bengal, Bihar, Eastern U.P., North Eastern Punjab, Eastern parts of Tamilnadu and the eastern slopes of Western Ghats receive moderate rainfall.

Area of Normal Rainfall:
The areas receiving rainfall between 50 cm and 100 cm come under this category. This category consists of Deccan Plateau, Western U.P., South Eastern Punjab, Eastern Rajasthan and parts of Kashmir.

Areas of Low Rainfall:
Western Rajasthan, Kutch, South Eastern parts of Haryana, North-Eastern Kashmir receive annual rainfall of less than 50 cm and hence called areas of scanty rainfall.

Question 4.
Describe the effect of climate on human life.
Answer:
The climate of a country affects its socioeconomic life. The effect of diversities of climatic conditions can be seen in our country also. Monsoon is said to be the center of Indian Economic life.

1. Due to the climates of India agriculture is normally possible throughout the year.
2. Amount of monsoon rainfall is sufficient for agriculture.
3. Different climates create favorable environment for the production of various crops.
4. Maximum rainfall is in the months of June, July and August which is beneficial for early ripening crops like jawar, bazra, and maize.
5. Fodder is also available due to rains which helps in cattle rearing.
6. The country remains dry or there are no rains for long period of the year, during which the grasses dry up resulting in scarcity of fodder. That is why there is no evergreen pastures or grazing land in the country.
7. Sultry hot weather is followed by widespread rains, which give rise to many diseases.
8. The uncertainty of rainfall highly affects the agriculture.
9. Drought and famine are the serious problems of Indian farmers. Heavy rainfall sometimes causes floods.
10. ‘Loo’ in the summer season makes the outdoor life very difficult.
11. Good quality is produced when adequate amount of rain is received in proper time. But if monsoon is late and amount of rainfall is less it adversely affects the agriculture.
12. Climate diversities result in the diversity in the forest resources, animal resources, industries, transport and human life.

Question 4.
Write a note on retreating monsoons.
Answer:
The months of October and November are known for the retreating monsoons. During this season the pressure in north – west India becomes weaker and shifts southward. In the first week of September they withdraw from Rajasthan. In November it is above Karnataka and Tamilnadu. By mid – December it retires completely from the peninsular plateau. Tamilnadu receives sufficient rainfall during retreating monsoon. But the rest part of India remains dry.

Question 5.
Describe the cold weather season or winter season of India,
Answer:
The Cold Weather Season. Cold weather season lasts from December to February. Temperature varies from 10° to 15°C in Northern plains to 22°C in the southern part of the Peninsula. Due to cold, high pressure is created in the plains. So the winds blow out towards the equatorial low pressure.

These winds are dry and cold. Most parts of India experience fine weather with clear skies and bright sunshine. This season is dry season for India except North – west part of India which receives rainfall from the Mediterranean and the coast of Tamilnadu which gets rainfall from the Bay of Bengal.

MP Board Class 9th Social Science Chapter 5 Long Answer Type Questions

Question 1.
Narrate the mechanism of the monsoons.
Answer:
The word ‘monsoon’ is derived from the Arabic word ‘mausim’ which means season. The formation of season is the chief characteristic feature of this climate. The world ‘monsoon denotes a season in which the wind regime is completely reversed. The direction of wind is reversed periodically. The reversal of direction of the monsoon winds is attributed to the difference in annual temperature on the land and on the sea.

Tire variation in temperature on the land and the sea creates high atmospherics pressure on the sea during summer and on the land during winter season which gives rise to the change in direction of the winds with a change in pressure of tire land. Thus, India which basically falls in the Trade winds zone experiences sudden reversal of winds from Indian Ocean to the land area.

This wind picks up moisture from the sea and enters the country through Arabian Sea and the Bay of Bengal. The Arabian Sea branch of the monsoons – is obstructed by the Western Ghats. The windward side of the Sahyadries receive very heavy rain. These winds then cross over the Western Ghats and cause rainfall in the Deccan Plateau, and Madhya Pradesh.

Thereafter they enter tire Ganga Plains and mingle with the Bay of Bengal branch. An other part of the Arabian Sea passes over the west Rajasthan and along the Aravallis, causing only a scanty rainfall. The Bay of Bengal branch moves towards the north – eastern coast and strikes the Arakan Hill along the Burmese coast.

But a big chunk of these winds is deflected and enters into the Indian sub – continent. This branch also splits into two parts, one part moving towards Ganga Plains and other towards Brahmputra Valley. Thus by July the entire country comes under the influence of monsoons.

Question 1.
Describe the drainage system of Northern India.
Answer:
The rivers of Northern India receive water from rainfall as well as melting of snow from ice-capped mountains. As these rivers flow through high mountains they form deep valleys, gorges and waterfalls. In their nature stage deposition in the plains take place. They form meanders, ox-bow lake and flood plains in their middle and lower course. Three large rivers originate from Himalayas:

1. The Indus River System:
This system comprises the Indus and its tributaires. The length of the Indus river is about 2900 km. It rises in Tribet near Mansarovar and flows towards west forming a beautiful 500 meters deep gorge in the Laddakh district of Jammu and Kashmir. From here it flows towards southwest, enters Pakistan and finally joins the Arabian sea. The five tributaries of Indus are Jhelum, Chin’ab, Ravi, Beas and Satluj. This region of five rivers is known as Punjab.

2. The Gangas River System:
The length of river Ganga is more than 2500 km. Its source is near Gangotri. The Ganga enters the plains near Haridwar. Its main tributaries are Yamuna, Ghaghra, Gandak and Kosi. These rivers form a fertile flood plain. They form meanders and ox-bow lakes. Near Ambala a water divide separates the Ganga and the Indus drainage system.

The Ganga receives some of its tributaries like Chambal, Ken, Betwa, Son and Damodar from the peninsular pleteau. Big dams have been built on these rivers which are used for hydro – electricity and irrigation. Flowing southward it forms a delta and finally joins Bay of Bengal. The main stream of the Ganges enters Bangladesh and when it joins Brahmaputra river it is called Meghana.

3. The Brahmaputra River System:
It rises near the Mansarovar iake and the Kailash mountains. It flows parallel to Himalayas and enters Arunachal Pradesh. In India it flows for 1400 km. Its tributaries include Dibang, Luhit, Dhansiri, Kalang etc. River courses often shift during floods. River islands are also formed. It is known as Tsangpo in Tibet, Brahmaputra in India and Padma and Meghana in Bangladesh. It forms a large delta and finally drains into Bay of Bengal.

Question 2.
Compare the rivers of Northern and Southern India.
Answer:
Rivers of Northern India:

• The rivers of Northern India have their origin in Himalayas and the Northern slopes of Peninsular India.
• Waterfalls are less.
• They are navigable.
• These rivers form deep valleys.
• These rivers form meanders.
• Receive water from melting ice and snow.

Rivers of Southern India:

• The rivers of Southern India have their origin in Western Ghats, Satpura and Peninsular Plateau.
• Waterfalls are more.
• They are not navigable.
• They flow in broad valleys.
• These rivers do not form meanders.
• Flow of water depends only on monsoon rainfall.

Question 3.
What is the importance of rivers in the economy? Explain.
Answer:
Rivers play an important role in the economy of our country. They are the lifeline of a country’s existence. Right from the beginning of the human civilization we have seen that people began to live on the bank of rivers. All the civilizations flourished there. The primary cause for this was that it had been the most convenient and cheapest means of transport. So, the trade and commerce flourished on the bailk of rivers. Most of the industrial towns have been settled along the river banks.

Dams and canals built on the rivers help us in our agriculture, which is the backbone of a country. We produce hydro -electricity from river water. Thus we see that rivers play a significant role in the economy of a country. Hence they must be protected from being polluted at all cost.

Question 1.
Describe the geographical division of India.
Answer:
India can be divided into the following geographical divisions:

1. The Northern Mountains
2. The Great Northern Plains
3. The Peninsular Plateau
4. The Coastal Region
5. Islands

1. The Northern Mountains:
The Himalayas in the north are the new fold mountains which extend from Kashmir to Arunachal Pradesh in the north of India. Their length is about 2400 km and width varies from 150 to 400 km. The Himalayas have three main ranges:

1. The Greater Himalayas,
2. The Middle Himalayas or the Himachal
3. Shivalik Ranges.

1.The Creator Himalayas or the Inner Himalayas or Himadri:
The Greater Himalayas are series of ranges which are always snow-capped. These ranges contain several high peaks which exceed, 8,000 meters above sea level. Mount Everest is the highest peak (8848 km) among them. In addition to that the Nanga Parbat, Kanchanjunga, Nanda Devi, etc. are some other high peaks. As these ranges remain always covered with snow so they are also called ’Himadri.

2. The Middle Himalayas or the Himachal:
Parallel to the south of the Greater Himalayas lies the rangers known as Middle Himalaya or Himachal. The height of these mountains varies between 3700 meters to 4500 meters and average width is 50 km. The Kashmir Valley and the Kangra and Kullu Valleys of Himachal are situated in these ranges. Pirpanjal and Dhauladhar are important ranges of this area. Hill stations like Shimla, Mussoorie, Nainital and Darjeeling belong to Middle Himalayas.

3. Shivalik Ranges:
These are the foot-hill ranges of Himalayas. They have an average height of 600 meters above the sea level. These ranges are often discontinuous. They have gentle slopes towards the north and steep slopes towards the . south. They represent the latest phase of folding and uplifting of the Himalayas.

In addition to these ranges, tine Zaskar and Ladakh ranges in Kashmir and the Kailash range in Tibet lie beyond the Himalayas. To the North-Eastern side of India lie the Naga, the Mizo and the Lushai hills. These hills are eastern extension of the Himalayas.

2. The Great Northern Plains:
The Great Northern Plains extend from the Punjab Plains m the west to the Brahmaputra valley in the east. This plain lies to the south of the Himalayas. This plain possesses the alluvial deposits of the Ganga, the Indus and the Satluj, etc. These rivers are perennial ones and flow down from the Himalayas. The average elevation of this plain is less than 300 meters above sea-level. The Ganga forms the largest part of it.

This region has rich alluvial soil and abundant water supply. So the means of livelihood are easily available here and the density of population is the highest. The Punjab plains forms the other part of the Great Norhtem Plain. The Brahmaputra valley in Assam forms the eastern part of the Great Northern Plain. It is narrower than the Ganga Plain. It is frequently flood area.

3. The Peninsular Plateau:
The Plateau has the central high lands in the north and the Deccan Plateau in the south. The Narmada Valley divides it into two major sub – divisions. Tire central high lands comprises the Malwa Plateau, the small plateau of Bundelkhand and the Chhotanagpur plateau. The hills of tire Eastern Ghats extend to the west of the Deccan Plateau.

The north western part of the Deccan Plateau in Maharashtra consists of an extensive ‘lava’ belt called the Deccan trap region. The rest of the Deccan Plateau consists of crystalline me tarn opine rocks The coastal plains lie both on the eastern and the western sides of the Deccan Plateau.

The Eastern Coastal Plain is broad. The alluvial delta plains of the Mahanadi, the Godavari, the Krishna and the Kavery are part of the Eastern Coastal Plains. The Western Coastal plain is, however, not so broad. In fact, the Peninsular Plateau is an old stable block or shield which consists of ancient crystalline rocks.

4. The Coastal Plains:
The Deccan Plateau is flanked by the narrow coastal plains along the Arabian Sea and the Bay of Bengal. The coastal plain on the western coast is narrow and uneven. The fast flowing rivers and streams dissect this strip at many places. It covers the plains of Gujarat in the north.

The eastern coastal plain is relatively wide and more level. It consists of some of the most fertile and well watered deltas of Krishna, Godavari, Mahanadi and Kaveri. The western coast has estuaries in the north and lagoons, the salt water lakes in the south particularly in Kerala.

5. Islands:
The coral islands off the coast of Kerala are Lakshdweep Island each having area of a few kilometers. This is a horse shoe form of island made by the continuous work of coral polyps. In the eastern parts lie Andaman and Nicobar islands in the Bay of Bengal. Some of these Islands are of volcanic origin and are fairly large in shape.

Question 2.
Describe the location and extent of India.
Answer:
India is situated in Northern Hemisphere in the southern part of the continent Asia. Towards its south lies the Indian Ocean. Bay of Bengal is in the east and Arabian sea is in the west. The latitudinal extent of the main land of India is 8°4′ North to 37°6’ North and the longitudinal extent is from 68°7′ East to 97°25′ East. The Tropic of Cancer (23°30’N) divides the country into almost two equal parts.

82°30′ is the standard meridian for Indian Standard Time. Standard time for the country is calculated from the stairdard meridian. Apart from the main land Andaman Nicobar Islands in the Bay of Bengal and Lakshadweep in the Arabian sea are also part of India. Tropic of Cancer divides the country into almost two equal parts.

Less area of India is situated on the eastern part of the standard meridian. The western c-f the country is Gujarat and the eastern state is Arunachal Pradesh. The northern most state of India is Jammu and Kashmir and the southern most state is Tamilnadu. The extreme southern point of India is located in Andman and Nicobar Islands.

India is bounded by Pakistan, Afghanistan in the north-west, China, Nepai and Bhutan in the north, Bangladesh and Myanmar in the east and Sri Lanka in the South. Palk Straight is between India and Sri Lanka. Coastal Boundaries of India , India is the seventh largest country in the world in regard to area. 2.42% area of the world is in India.

Question 4.
Describe the Peninsular Plateau.
Answer:
The Peninsular Plateau is a part of the oldest landmass the Gondwanaland. Its average height from the sea level is 600 to 900 meters. It is surrounded by seas from three sides and by landmass from one side so it is also known as Peninsular Plateau.

It is a triangular plateau with its base in the north, from Delhi, and Rajmahal Hills to northern plain. It is bordered by the Eastern Ghats in the east and by the Western Ghats in the west and Kanya Kumari is at the southern tip. Regarding area, the peninsular plateau is the largest physiographic division of the country.

The peninsular plateau is divided into two parts –

1. The Central Highlands.
2. The Deccan Plateau.

1. The Central Highlands:
The Northern part of the peninsular plateau comprises of plateaus, uncovered mountain ranges and low mountains. It is made up of hard igneous rocks. In the north-west it is flanked by the Aravallis, which are old folded mountains. On the southern boundary of the Central Highlands lies the Vindhyachal Mountains and it continues to the Kaimur range eastward. The Malwa Plateau lies in between Amrawati and Vindhyachal mountains.

This Plateau is drained by the Betwa, Parvati, Kali Sindh, Chambal and Mahi. The eastern part of the Central Highlands is known as Bundelkhand. The Baghelkhand Plateau is situated in the east of Kaimur Bhander hills. In the central part of Highlands Vindhyachal and Kaimur hills form an escarpment between the valleys of Narmada and Son rivers. The Chhotanagpur Pleteau of Jharkhand is also a part of this region. It is rich in minerals.

2. The Deccan Plateau:
It extends from Satpura, Mahadev and Maikal hills in the north to the southern tip of peninsula. The north-western part of the plateau is mainly made up of volcanic deposit. The Western Ghats, from the western edge of the Deccan plateau, which run discontinuously from north to south almost parallel to the Arabian Sea. In Maharashtra and Karnataka they are called Shayadri.

The Ghats are crossed by three gaps:
Thalghat, Bhorghat and Palghat. They are called the Nilgiri’s in Tamilnadu and along Kerala and Tamilnadu borders, they are known as Anamalai and Cardamon Hills. Palghat gap separates Nilgiri and Anamalai Hills. The highest peak of Southern India, The Anai Mudi is in Palni Hills. The Eastern Ghat is 800 km. long. Its highest peak is Mahendragir.

Question 5.
Write Short notes on Indian Coastal Region, Indian Islands.
Answer:
Indian Coastal Region:
The Peninsular Plateau of India from Kutch to Orisa is flanked by a narrow strip of coastal lowlands ‘or plains. Due to difference in their formation, this coastal plain is divided into two parts:

1. The West Coastal Plain.
2. The East Coastal Plains.

Answer:
The Deccan Plateau lies to the south of the Indogangetic plain. It is triangular in shape. It is bounded in the north by the Vindhyas and Satpura hills while its eastern and western boundaries are formed by the Eastern and Western Ghats. Its surface is uneven and rocky.

The soil is not as fertility as in the northern plain. Since the Deccan Plateau is formed of hard igneous and metamorphic rocks, the soil is black and literate. It is not as fertile as the alluvial soil of north plains. The average height of Deccan Plateau is about 600 feet.

This area comparatively receives less rainfall as it is surrounded by mountains from all around. The Krishna, the Godavari, the Mahanadi and Kaveri are the chief rivers. In this region, these rivers are swift and make waterfalls so they are not navigable. These rivers form big deltas at their mouth. The Deccan plateau has a coastal strip in the east and the west. The west coastal plain extends from Gujarat to Kerala.

The coastal strip along the Arabian Sea in the west is known as Konkan in the north and Malabar in the south. In the south, there are south salt water lakes called Lagoons. The coastal strip along the Bay of Bengal is broad and more leveled. The mountain ranges running from north to south along the Arabian sea coast has many names.

In Maharashtra and Karnataka they are called Sahyadri. Further in south, they are called the Nilgiries, in Tamil Nadu along the Kerala and Tamil Nadu border, they are known as Annamalai and Cardamon Hills. The Deccan Plateau is highest along its western edge and slopes towards the Bay of Bengal.

What is the meaning of the Chipko Movement? How was it started and what were the reasons of its international fame?
Answer:
Chipko Movement was started in 1974 in Chamoli district of save trees. The women of that district in absence of menfolk came forward to resist cutting of trees by the forest laborer. They were saying that the forest is their parental home. They would not let it cut at any cost. They embraced trees for continuous two days and nights.

This movement was called Chipko Movement, In 1974 an Allahabad-based sports production company named Simond was given contract of cutting trees of Anguspecws in Chamoli district. The decision of auction of hundreds of acres of forest area found in the Renigaon of Chamoli created much dissatisfaction among the people. The forest department tried to pacify their revolt by inviting the menfolk of Renigaon and nearby villages to Chamoli for the payment of compensation for the role they had played during war time.

At the same time forest workers and laborers reached Renigaon to cut trees. The women of that village, in the absence of menfolk, came forward to resist cutting of trees by the forest laborers. They were saying that the forest is their parental home. They embraced trees for continuous two days and nights. They also broke the one arid only bridge of the entrance of the forest.

After this event Rigatoni became the battlefield of Chipko Movement. All over the Uttarakhand, people witnessed a new zeal to protect forests after this event. In order to speed up this movement Sundarlal Bahuguna walked 2800 km. Finally the State Govt, banned felling of forests in Renigaon area.

Question 3.
Describe in detail t’e efforts for water conservation in Madhya Pradesh.
Answer:
When the forest in Jabua district of Madhya Pradesh were ruthlessly cut, the land begar to decrease its fertility. Consequently soil erosion increases and employment opportunities reduced. It was due to this reason that the local population began to migrate. In the year 1994 the Rajeev Gandhi Water Storage Mission was started to elevate the problems of drought and deforestation.

This mission involves consumer at the end point with land and water conservation programmed, specially stressing on his participation in the ongoing process and in maintenance. Under this mission stop dams and ponds were constructed for water storage on local public demand. As a result the quantity of available water increased, soil erosion was prevented, water became easily available for irrigation, plants and animals.

In 1999 the State Government made it compulsory for the Sarpanch of every Panchayat under ‘Ek Panch Ek Talab’ scheme to construct at least one new pond and reform the old during his office of five years. Thus, about 3412 ponds were rebuilt and 500 new ponds were constructed in a duration of less than 15 months. One-fourth of the cost was borne by the people. In the year 2000 under the ‘Pani Roko Abhiyan’ water storage was increased by making small dams.

This resulted in the development of 7 lacs water catchment area. Under the ‘Gaon Ka Pani Gaon Main Evam Khet Ka Pani Khet Mein’ programme, water was stored in the farms by constructing hedges. The efforts of water conservation made in Madhyi Pradesh were followed by other states too.

Question 1.
Describe the methods of Environmental Impact Assessment
Answer:
Environmental Impact Assessment is conducted in three stages:
Initial Scrutiny, Rapid Environmental Impact Assessment and Comprehensive Impact Assessment. Initial screening of a project is done to decide whether the impact assessment is actually needed for the project being under taken or not. If it is felt that the project is likely to cause some adverse effects on the environmental, it is subjected to Rapid Environmental Assessment.

Rapid Assessment attempts to identity the key issues in a particular project. Issues which are not important enough to require further studies are omitted. Comprehensive Environmental Assessment is undertaken after the Initial and Rapid Impact Assessment have been performed. Critical aspects of the project are taken up at this stage. If needed, the project may not be approved for implementation.

It has become a common practice to use plenty of in – pesticides to enhance production. As a result the nutrients of the soil are reduced. The fertility of soil is also hampered. The quality of production is affected.

Question 11.
What are the harmful effects of mining on the environment of a region?
Answer:
Excessive mining means digging of land for extracting minerals and other substances. Trees are being cut from the land. As a result circulation of underground water is hampered, land sliding, deposition of waste material, soil erosion and formation of new’ land forms occur. The ill – effects of excessive mining can be observed in Doon valley formed by Ganga – Yamuna which are surrounded by Himalaya ranges.

Previously this valley area was world famous for the production of Basmati rice, litchi and tea. But now due to uncontrolled mining of lime stone only 12% valley area has greenery. In the Jaipur, Jodhpur and Udaipur districts due to mining of stones the surrounding greenery has been destroyed.

Question 12.
How does urbanization destroy the environment?
Answer:
As a result of urbanization there is increase in population density and transport facilities, roads, railways, hospitals, community centers etc. are on rise. All these increase the pollution. The increasing deposition of waste influences the environment also.

Question 1.
Explaining the Indian concept of environment describe how man is related to his environment?
Answer:
There has always been a mutual relationship between man and nature. We can find proof in regard in our ancient literature too. Nature is represented in the form of mother in Vedas. In the hope of healthy environment man has maintained passionate relations with the environment in his life-style. His debt towards environment is exposed in the form of sensitivity, honor, passion, and safety.

Man and environment are the creator, parent and savior of each other. Nature is considered as the substitute of life. We have always offered our prayers to water sources such as the Ganga, the Yamuna, the Saraswati, plants like the Banyan, Peepal, Neem, and Tulasi. We have always worshiped the Sun, the Moon and the.

Earth. In turn the mother nature has brought up us like her children. It is believed that the environment receives fragrance as we bum Dhoop. The up nishads assume earth as body of the supernatural, heaven as his brain, the Sun and the Moon as his eyes and skies as his mind. Hence, it is not proper to cut trees and pollute sources of water. Thus, we can say that man and environment are closely related with each other.

Question 2.
What is environment? What are the main elements of environment? How has man affected the environment? Explain.
Answer:
All that surrounds us is our environment. Environment consists of all living and non-living matter that exist around us. There is a close relationship between man and environment. Man is born in his special environment and passes his entire life in the same environment.

Environment may be defined as follows:

• The environment is all that surrounds mankind and directly or indirectly influences man.
• All physical elements and biotic elements together constitute environment.

Main Elements of Environment:.
All the elements which effect environment are called the elements of environment. These elements can be classified into major categories.

1. Elements of natural or physical environment:
This includes all natural elements given by the nature such as location, geomorphology, rocks, climate, vegetation, wild life, minerals, water bodies, ocean, etc.

2. Elements of Sociocultural Environment:
The sociopolitical environment develops due to the mutual relationship between man and natural environment. This includes the economic and social activities created, developed and conducted by man such as farming, industry, rites and rituals, settlement, roads, railways, air, services, means of irrigation, government system and science and technology.

3. How has man affected the environment?
Man is at the top of ecological pyramid. He is omnivorous because he. feeds both on plants and animal life. As a result of senseless and. continuous hunting, some species of birds and animals have become extinct and others are leading to extinction. Cultivation of land has had a serious impact on ecosystem.

The removal of original plants covers and its replacement by single cultivated crop reduces the biological diversity and simplifies the ecosystem  making it venerable to pests and diseases which attack crop. Burning of fossil fuel in large quantities, automobile exhausts, gaseous effluents from factories have led to the pollution of air and water.

Humans have cleared the jungles for their dwellings, for rearing animals and for construction roads and buildings. Too much use of land, forests have caused lot of health problems and ecological problems. As a result of pollution of air and water various species of plants have became extinct because pollution of air and water adversely affects plants.

Question 3.
What do you mean by pollution? Describe differ- it types of pollution.
Answer:
Pollution. The undesirable change in the physical, chemical, and biotic elements of the environment which adversely alters the natural quality of the environment is called environmental pollution. Pollution of the environment may occur naturally without the intervention by human being or may be caused by human activities. Volcanic eruptions, forest fires, space disturbances are the examples of pollution’s caused by nature itself. But pollution is mainly caused by human activities due to over-use, misuse, and mismanagement of resources.

Types of pollution:
1. Air pollution:
Disturbance of balance among various gases in the air or presence of unwanted gases is known as air pollution. The burning of fossil fuels in large quantities during the recent ‘ decades had resulted in gradual increase in carbon – di – oxide content in the atmosphere. The increase in carbon – di – oxide leads to increase in temperature.

Burning of coal and oil adds sulphur dioxide to the atmosphere which causes many body aliments including respiratory diseases. Gaseous effluents from factories also pollute the atmosphere. Air pollution is of global significance unlike water or land pollution which are of local or regional effect. These gases also cause acid rain in industrial regions affecting acquainted ecosystem.

The water so polluted cannot support fish or other life forms in water. Acid rain also damages forests. The ozone layer in the atmosphere serves as a shield protecting the earth from ultraviolet radiation. When the ozone layer is depleted, ultraviolet radiation enters the earth surface and may cause skin cancer.

2. Water Pollution:
The entry of some unwanted substances in the natural water that reduces its purity is known as water pollution. Polluted water is not suitable to men, animals, vegetation, sea, animals and irrigation. The causes of water pollution are soil erosion, leaves of trees, domestic drainage, and sewage, effluents from factories, fertilizers and pesticides and the hot water flowing from nuclear reactors and spreading of mineral oil on sea surface. This contaminates the drinking water and causes water born diseases such as jaundice, dysentery, and typhoid. etc. .

3. Noise Pollution:
The disturbance caused by noise or unwanted sound which interferes with human communication, comfort and health etc. is called Noise Pollution. The problem of noise pollution is very acute in urban areas due to sound produced by different vehicles, machines, transistors and radios, drum beats on religious and wedding procession amplifier rock music and discos etc.

Constant exposure to this sound produces deafness, increase in nervous tension, blood pressure and causes heart troubles. It also causes headaches, irritability and affects the sensory and nervous system.To control noise pollution, improvement in the machines, construction of sound barrier and absorbs, should be done. The ear protective devices should be used.

4. Soil Pollution:
Any unwanted change in the physical, chemical or biological attributes of the earth which destroys the fertility and utility of. land is soil pollution. Excessive use of pesticides and fertilizers, industrialization, urbanization, plastic and polythene, continuous irrigation with salted water, etc. are various causes of soil pollution.

5. Radioactive Pollution:
During the use of nuclear elements for various purposes the radioactive particles enter the atmosphere and produce radioactive pollution. The excessive energy released during nuclear test’ destroys human and animal cells.

6. Thermal Pollution:
An unwanted increase in normal temperature in the world which effects biosphere is thermal pollution. Carbon-dioxide, methane, CFC, Nitro-us oxide, ozone hole, forest fire, nuclear tests etc. increase atmospheric temperature. Drought, flood, low agricultural production due to climate change, ozone depletion etc. are some of the ill-effects of thermal pollution.

Question 4.
What is the meaning of resources? Describe various types of resources with example.
Answer:
All the elements, biological or non – biological, present in nature which are capable of fulfilling human wants are called resources. Land soil, water, air, sun – rays, forests, wild animals, fish, minerals etc. are examples of resources.

All gifts of nature about which man has the knowledge in regard to their use, availability and accessibility are thus called resources. There may be innumerable things hidden in the lap of nature but man may not be knowing about many of them. Thus gifts of nature, about whom man does not know, cannot be called resources.

Various Types of Resources:

• Natural Resources – Renewable (air, agricultural, water, forest), Non – renewable (non-cyclic fossil fuel, as coal, petrol and cyclic-metallic minerals).
• Human Resources – (population, health, education and working efficiency).
• Man – made Resources – (buildings, roads, sociopolitical institution).

1. Renewable Resources:
Resources, which are reproduce-able after the use or can be used again eg. forests, pastures, agricultural land.

2. Non-renewable Resources:
Those resources which once exploited cannot be reproduced or supplied in tire near future such as petroleum, coal.

3. Human Resources:
It means the number and quality of human beings. Education and health increase man’s physical and mental capacity. Man himself is major resource who uses the natural elements as resource on the basis of his knowledge, labor and technical know – how.

4. Man – made Resources:
These are those means of production which are produced by man to utilize the physical matters of environment such as machines, buildings, tools, etc.

5. Land Resources:
It is an important natural resource. Land is used for housing, roads, railways, farming, pasturing and mining, etc.

6. Water Resources:
Water on the earth surface is obtained through rains, rivers, lakes, ponds, glaciers, waterfalls and tube- wells. The water is used for irrigation, industry, domestic supply, fish farming and water transport.

7. Soil Resources:
Good soil is essential for the growth of vegetation.

8. Forest Resources:
Forests are a valuable resources like rivers. Forests provide us many valuable products timber, paper, medicine, firewood, wood pulp, lac, rubber, etc. Forests check soil erosion. Forests prevent floods. Forests provide suitable environment for wild-life. Forests absorb carbon – dioxide and release oxygen to the atmosphere. Forests add water vapor to the atmosphere by the process of transpiration.

Question 5.
How does changing use of land affect the environment? Explain.
Answer:
Man has brought many changes in environment in order to fulfill his ever-growing needs. He has made unnecessary disturbance in natural environment. The major cause of decline of natural environment in the world is changing form of land-use. In India forests are being destroyed for various purposes.

Deforestation and pasturing, construction of big dams for hydro – electricity and irrigation, spread of new roads and railways and development of factories has transformed land – use in India to a great extent. This has disturbed the natural balance.

The continuous interference with environment for the sake of human settlement and industrial and economic development cause environmental deg – radiation. The habitat of various types of animals have been destroyed and thousands species of flora and fauna become extinct.

Question 6.
How does over-population affect human life? Explain.
Answer:
When the population of country rises at such a fast speed that existing resources of the country fall short of the necessity of the people, it is called stage of over – population or population explosion. This has created many problems such as crowd, unemployment, security of resources, pollution, mental and social tension etc.

In the absence of suitable dwelling arrangements people tend to live on fields, streets and lanes. This gives rise to the establishment of jhugg is and subsequent loss to the ecological balance. Over – population has created the problem like overcrowding. It leads to pollution – which leads to many health hazards.

Due to over – population various types of resources are decreasing fast. People cut trees which has created grave situation. People are in race of acquiring more and more material objects. This race has given them mental and social tension. This, over – population has badly affected the human beings. We remain under pressure all the time which may reduce our life span.

Question 7.
How is the construction of huge dams harmful for the environment? Explain.
Answer:
Dams are being constructed on big rivers for purpose of irrigation, hydro – electricity, canals, fishing, water transportation and flood control. About 700 dams have been constructed after independence. But they are not unbeatable from the point of view of environment. Whenever a river valley project is started the construction of houses for the workers, construction of road, railway and underground tunnels become essential.

As a result the greenery of large areas surrounding the construction site disappears. The artificial pond made from the huge dam drowns forests and farm land. The alkalinity of the land increases due to water drained from the canals of the dam and its fertility decreases. Due to the prevalence of continuous water in dam and canal area the nearby land becomes unsuitable for agriculture. Human settlements are displaced from the dam area. Thus construction of huge dams badly affects our environment.

Question 8.
Centralization of industries is very dangerous for the environment. Explain with examples.
Answer:
Industrialization is helpful to man but harmful to our environment. The factories release poisonous gases in the atmo sphere. This disturbs atmospheric balance and increases air pollution. The waste material are left open in surrounding areas. The polluted water is drained in the river which directly influences human health and environment.

Industrialization is the main source of air, water, noise, land, chemical and radioactive pollution. In the Kolkata metropolis of India the water of Damodar and Hugh rivers have been poisoned by the effluents of surrounding steel factories, chemical industries, distilleries and paper and jute mills. Same is the true with the Ganga, Yamuna and Chambal rivers.

Question 9.
What do you mean by water pollution? River pollution is increasing in India. Describe.
Answer:
The entry of some unwanted substance  in the natural water that reduces its purity is known as water – pollution. Water is being polluted by the humans in different ways.

1. When factories, specially, those of paper mills, sugar mills, tanneries etc. discharge their effluents in rivers or allow them stagnate on land.

2. When there is no river nearby the stagnated effluents seep through the land, mix with the underground water and pollute the water. For example, effluents from large number of tanneries in North Arcot district in Tamilnadu have polluted well water in large number of villages.

3. The most widespread source of water pollution is disposal of sewage of urban centers into river. For example, rivers Ganga, Yamuna are polluted by sewage disposal while these rivers also provide drinking water to the people residing nearly.

This contaminates the drinking water and causes water born diseases such as jaundice, dysentery and typhoid etc. Approximately 90% surface water is polluted in India. The Ganga, Hugh, Damodar, Gomti,t Yamuna, Godawari rivers are polluted due to the industrial and the urban wastes and sewages.

MP Board Class 9th Social Science Chapter 1 Long Answer Type Questions

Question 1.
Describe the factors which are responsible for the changing form of land all over the world.
Answer:

There are many factors which are responsible for the changing form of land all over the world:
1. Population Growth and Reproduction:
Our population is increasing day by day. As a result we are facing the problem of population explosion. Human life-style has improved due to progress in the field of medicine. The fertility and mortality rates have come down. Deaths are on decline. As a result mortality rate has unexpectedly gone down and population has gone up. Due to unlimited growth in population problems like crowd, unemployment, security of resources, pollution, mental and social tension have come up.

2. Deforestation:
It means cutting forests or plants from some region. Reduction of forest is the result of human effects. All methods of shifting cultivation made enough harm to the forests. Other factors which have harmed forests are construction of huge dams, spread of railways and roads, etc.

3. Excessive Grazing:
As a result of excessive grazing the vegetation does not grow again very fast in these areas. The ill- effect is that layer or vegetation from land is destroyed. Due to soil erosion the danger of desertification arises.

4. Harmful Experiments in Agriculture:
In order to fulfill the ever-increasing demand of food crops of more production are grown. It is a common practice to use plenty of chemical fertilizers, pesticides and weed killing chemicals to en-chance production. Salination increases as a result of inadequate drainage of water from the fields. Nutrients of the soil are reduced due to prevalence of excessive water.

5. Urbanization:
It has increased population density, and transport facilities. Roads, railways, hospitals, community centers etc. are on rise. Some other factors are industrialization and extension of slums and construction of huge dams.
