Question 6.
Describe the atmosphere conditions on the basis of following isobar?
MP Board Class 10th Social Science Solutions Chapter 5 Map Reading and Depiction img 4
MP Board Class 10th Social Science Solutions Chapter 5 Map Reading and Depiction img 5
Answer:

  1. Is cyclone and
  2. Is anti – cyclone.

In cyclone when the isobars form concentric closed circles, the smallest circle in the center indicates a low pressure center. Air moves from a high pressure area to a low pressure area. In the Northern Hemisphere, the wind blows in a counter clock – wise direction in a cyclone. In the Southern Hemisphere, the wind blows in a clock – wise direction. These cyclones move in the direction of pressure center.

Air pressure in little in the center of shallow depression but it is very little in deep depression. Deep depression is surrounded by more than one isobar and shallow depression area is surrounded by single isobar and partially surrounded by other isobars. Isobars are depicted in a dispersed way in shallow depression and the isobars are shown close in depression. Under this condition the air mass rises above and takes the form of clouds and rains. Thus the weather conditions are rough in the cyclonic area.

The Anti – cyclone is opposite of cyclone. Anti – cyclone have high pressure in the center and they are surrounded by low pressure. The center of high pressure is called ‘Highs’. This is the point of intersection of two wedge lines. The isobar is usually circular, the winds blow in clock – wise direction in the Northern Hemisphere and counter clock – wise in the Southern Hemisphere.

The winds blow outwards from the center in such condition. Anti – cyclone are weak and stay at one place for quite some times. The wind is slow and keep varying. Anti – cyclone do not move in a definite direction and the center is calm. In the front the winds blow in a definite direction; the sun is bright and sky is clear and dry. Sometimes there are drizzling rains.

Question 1.
Describe the importance of weather maps. Where we can use the information of weather forecast which in shown in weather map?
Answer:
Need and importance of the study of weather map:
With the help of weather maps it is possible to know in advance the weather conditions, these forecasts are published in news – papers and broadcasted through ’Akashvani’.

Through these forecasts efforts are made to provide safety and security to the people in times of natural calamities like excessive rains, (and consequently floods etc.) inadequate rains (and draught conditions as a consequence), earthquake, hailstorm, cyclones, snow fall, etc.

The forecasts made on the basis of weather map help in talking suitable safety measures at the time of navigation safe aeroplanes, flights, and drought conditions and their ill effects and properly carrying out the agricultural operations.

Question 5.
How cyclone and anti – cyclone are formed?
Answer:
Cyclone and anti – cyclone are formed due to the contact of two different types of wind. The contact point is known as a surface of separation.

Question 6.
What do you mean by wedge? Also, define crest line?
Answer:
Wedge is a triangular high pressure area. The isobars are V – shaped with rounded peak. The peak indicates towards the low pressure area. In the center of the edge, the air pressure is the highest and it goes on diminishing towards the peak and edge. The line joining the highest pressure point and the peak point it called crest line.

Question 4.
Explain the variation of air pressure with the help of Indian map and draw the conclusion related to the trends?
Answer:
Variation in air pressure:

In the weather map the air pressure is shown with the help of millibar. This is normally indicated by the difference between two millibars. The higher number shows high air pressure and the lower number shows low air pressure.
Sometimes low pressure is indicated by writing L and high pressure by H. This is read like contour lines. The air always blows towards low pressure area from the high pressure area.

1. Normal distribution of air pressure:
High and low pressure zone.

2. Speed of cyclones:
With the help of the air pressure map, we can explain the conditions of air pressure in the atmosphere. From the map given we see that the air pressure was 2 millibar less than the normal. Only in two zones the pressure was normal. The mountain region of North, Bihar, Andaman and Nicobar and Eastern Myanmar the air pressure was normal.
