Question

Write a short note on effects of planetary winds.

Answer 1

1. The winds that blow continuously and regularly above the world pressure belts are known as planetary winds.
2. These winds play a crucial role in transporting heat and moisture across the world. That is why no part of the world gets too cold or too hot for life to survive.
3. If there was no atmosphere (as on the Moon) it would have got intolerably hot during day or in the tropics and intolerably cold at night or in the Polar regions.
4. However, these winds do not distribute heat or moisture uniformly – which is why some parts of the earth are quite hot, some parts cooler and some parts with high rainfall and some which are deserts.
