Question

Write about the cause of wind.

Answer 1

Wind:

1. The uneven heating of land and sea results in an unequal expansion of air.
2. The air that is in contact with hot surfaces gets heated by conduction and rises since its volume increases, thereby decreasing the density.
3. The rising of this heated air causes a low-pressure zone that attracts air from the surrounding regions.
4. Thus, a recurring cycle of heated air rising and being replaced by air from high-pressure sets in. This unequal heating of land and sea and the movement of air resulting from it gives rise to winds.
