Question

What causes winds?

Answer 1

Wind:

1. The uneven heating of land and sea results in an unequal expansion of air.
2. Solar radiation heats the surface of rocks, soil, and the entire landmass.
3. The air that is in contact with hot surfaces gets heated by conduction and rises since its volume increases, thereby decreasing the density.
4. The rising of this heated air causes a low-pressure zone that attracts air from the surrounding regions too.
5. Thus, a recurring cycle of heated air rising and being replaced by air from high-pressure sets in.
6. This unequal heating of land and sea and the movement of air resulting from it gives rise to winds.
7. Winds result in the formation of depressions, anticyclones, fronts, convection currents, and advection. Each of these weather systems has a varied impact on the climate.
