Differentiate between all 4 pressure belts.
Answers
Answer:
These belts exist in pattern of alternate high and low pressure zones over the earth and they are four in numbers: equatorial low pressure belt, sub-tropical high pressure belt, sub-polar low pressure belt and polar high pressure belt (Figure below).
Answer:
(i) Equatorial Low-Pressure Belts
This low-pressure belt is also called as doldrums because it is a zone of total calm without any breeze.
(ii) Sub-tropical High Pressure Belts
The subtropical region blow towards the Equator as Trade winds and another wind blow towards Sub-Polar Low-Pressure as Westerlies.
(iii) Circum-polar Low Pressure Belts
Centrifugal forces operating in this region create the low-pressure belt appropriately called Circum-polar Low-Pressure Belt.
(iv) Characterized by permanent IceCaps, also at the North and South Poles, between 70° to 90° North and South, the temperatures are always extremely low.
