Question

What are permanent pressure belts . Why are they present on the surface of the earth​

Answer 1

Explanation:

The cold descending air gives rise to high pressures over the Poles. These areas of Polar high pressure are known as the Polar Highs. These regions are characterised by permanent Ice Caps. If the earth had not been inclined towards the sun, the pressure belts, as described above, would have been as they are.
