Question

what causes the wind to blow​

Answer 1

The difference in the atmospheric pressure of two regions makes air from high pressure to flow to low pressure. This makes the flowing wind.

Answer 2

Wind is caused by differences in the atmospheric pressure. When a difference in atmospheric pressure exists, air moves from the higher to the lower pressure area, resulting in winds of various speeds. On a rotating planet, air will also be deflected by the Coriolis effect, except exactly on the equator.
