Question

write any Four Points on pressure belts and planetary winds

Answer 1

There are a total of 7 Pressure Belts on the surface of Earth viz., Equatorial Low, 2 Sub-Tropical Highs, 2 Sub-Polar Low, and 2 Polar Highs. All others exist in corresponding  Northern and Southern Hemisphere except the Equatorial Low Pressure Belt.

1) The Equatorial Low Pressure Belt extends from 0 to 5° North and South of the Equator and is the most hot portion of earth as the rays of sun have the highest intensity in this zone.

2) Sub-Tropical Pressure Belts or the Horse Latitude exist in 30° North and South of the Equator and here the upward moving equatorial air currents descend down.

3) Sub-Polar Low Pressure belts are found between 60° and 70° in both the hemispheres.

4) Polar High Pressure Belts or Polar Highs exist in between 70° and 90° North and South and here the temperatures are consistently very low. So, the permanent ice caps are present here.


Planetary Winds are similar movement of air that appear with high variations on worldwide scale. They blow in the same direction throughout the year. They are uniformly distributed on the entire surface of earth. They are, thus, prevailing winds or permanent winds viz., Trade Winds, the Westerlies and the Polar winds.

Answer 2

Explanation:

Answer: Permanent winds are winds that blow between the major pressure belts of the world. ... They are of three types- trade winds, westerlies and polar winds. The Trade winds: The trade winds blow from the sub-tropical high pressure belts to the equatorial low pressure belt.
