What causes air to flow?
differential pressure
Air flows due to differences in air pressure. Air moves from areas of high pressure to areas of low pressure, which creates air currents or wind. The greater the difference in pressure between two areas, the faster the air will flow. This pressure gradient can be caused by a variety of factors such as temperature variations, altitude differences, and the movement of weather systems like high and low pressure fronts. Additionally, air can also be forced to flow by physical obstacles, such as mountains, or by the rotational forces of the earth, known as the Coriolis effect.
