Question

Quizplus · Accepted Answer

When wind blows over the top of a hill, it creates a zone of low pressure on the windward side of the hill. This happens due to the fact that the air molecules are forced to move upward and away from the surface of the hill. As a result, the air pressure decreases in this zone. On the other hand, on the leeward side of the hill, the wind pushes air downward, which creates a zone of high pressure. Therefore, the wind blowing over the top of a hill decreases atmospheric pressure on the windward side of the hill.
