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.

Temple,
Metalled road,
Post Office
Broad guage rail line
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.

Answer:

Conical Hill – Contours are concentric circles drawn at uniform interval.
Plateau – The top of left flat without contours; on the sides, contours are closed.
Ridge – Contours are elongated circles.
Valley – Contours are inverted V’ shaped.

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.
