The two Temperate Zones maintain a moderate climate.

geography pressure belts and winds pressure belts elements of weather and climate :rainfall and air pressure monsoon phenomena and its mechanism

  1. True

  2. False

Show answer
Correct Option: A
Explanation:
True.
In geography, temperate latitudes of the Earth lie between the subtropics and the polar circles. Temperate means moderate. Unlike in the tropics, temperatures can change greatly here, between summer and winter. So, most places with a temperate climate have four seasons: summer, autumn, winter and spring.

Earth rotates from ______________.

geography atmosphere and climate pressure belts elements of weather and climate :rainfall and air pressure monsoon phenomena and its mechanism

  1. East to west

  2. West to East

  3. North to South

  4. South to North

Show answer
Correct Option: B
Explanation:

West to East,

Earth's rotation is the rotation of Planet Earth around its own axis. Earth rotates eastward, in prograde motion. As viewed from the north pole star Polaris, Earth turns counterclockwise.
Because Earth rotates on its axis from west to east, the Moon and the Sun (and all other celestial objects) appear to move from east to west across the sky. Viewed from above, however, the Moon orbits Earth in the same direction as our planet rotates.

The prevailing winds blowing from $30^\circ S$ and $30^\circ$ N towards the equator are termed as ______.

  1. Monsoon winds

  2. Antitrade winds

  3. Trade winds

  4. Polar winds

  1. kal baishaki

  2. trade winds

  3. loo

  4. western disturbance

Show answer
Correct Option: C
Explanation:

Loo is the hot wind blowing during the hot westher season. It is strong and dusty wind. It blows during day time over northern and northwestern india. 

What is the percentage of wind eroded area in India?

geography winds pressure belts elements of weather and climate :rainfall and air pressure monsoon phenomena and its mechanism

  1. 10%

  2. 15%

  3. 20%

  4. 14%

Show answer
Correct Option: A
Explanation:
  • Among the two main agents of erosion in India, wind erosion contributes to erosion in close to 10% area in India. Approximately 90% area is eroded by water.
  • Hence option A is correct.

In India, which coast receives rainfall from North East monsoon ________________.

geography winds pressure belts elements of weather and climate :rainfall and air pressure monsoon phenomena and its mechanism

  1. Konkan Coast

  2. Malabar Coast

  3. Coromandal Coast

  4. Gujarat Coast

Show answer
Correct Option: C
Explanation:

Coromandal coast receives winter rainfall because of the retreating monsoon and the North-east Monsoon winds which pass over the Bay of Bengal. There they get moisture and when they reach the Tamil Nadu coasts they cause rainfall there. During the winter season, the northeast trade winds prevail over the country.

The subtropical high pressure belt is often called _________ .

geography pressure belts and winds pressure belts elements of weather and climate :rainfall and air pressure monsoon phenomena and its mechanism

  1. doldrums

  2. ITCZ

  3. horse latitudes

  4. none of the above

Show answer
Correct Option: C
Explanation:

The subtropical high pressure belt is often called horse latitude. It is situated around $30^o$ Northern and Southern hemisphere.

The monsoon winds are known as the seasonal winds.

geography winds pressure belts elements of weather and climate :rainfall and air pressure monsoon phenomena and its mechanism

  1. True

  2. False

Show answer
Correct Option: A
Explanation:

The monsoon is a seasonal modification of the general planetary wind system. Monsoon winds are most powerful India and China. During summer, the interior of Asia become hot and low pressure develops there. On the other hand, the water surface of Indian ocean remains cooler and the pressure gradient is towards the heated interior. So monsoon wind blows from water to land, it is moist and brings lots of rain. In winter the water is warmer than the land surface. As a result, the wind blows from the interior towards the ocean so it is cold and dry. 

Wind rose consists of ______ made up of _________ compass points.

geography winds pressure belts elements of weather and climate :rainfall and air pressure monsoon phenomena and its mechanism

  1. Octagon , 8

  2. Hexagon, 6

  3. Polygon, 2

  4. None of these

Show answer
Correct Option: A
Explanation:

Wind rose is a tool which gives us the idea of how typically the speed and direction of the wind are distributed at a particular location. It consist of 8 compass points. 

What is Wind Rose?

geography winds pressure belts elements of weather and climate :rainfall and air pressure monsoon phenomena and its mechanism

  1. Flower

  2. Instrument to measure wind flow

  3. Instrument to measure wind speed and direction

  4. None of these

Show answer
Correct Option: C
Explanation:

Wind Rose is the instrument to measure wind speed and direction of the wind. They help to identify the direction and frequency of wind in a particular place. One of the important use of Wind Rose in the construction of airport runways, so that the airplane can take the best takeoff and landing point towards and away from the wind.
