Why does air blows from one place to another

Air blows from one place to another because gases move from high-pressure areas to low-pressure areas

In simple words

it happens because of pressure differences.

Gases moving from high-pressure places to low-pressure places. The bigger the difference of pressure the faster the air moves from both. Giving the movement of air we experience.

OR:

The high-pressure air will raise up to the low-pressure air and will come down causing the air will blow from one place to another.
