Question

Quizplus · Accepted Answer

Air molecules in high pressure zones are more tightly packed and therefore move towards low pressure zones where the air molecules are less tightly packed. This movement is in accordance with the pressure gradient, which is the change in pressure over distance. Therefore, air moves from high to low pressure zones along the pressure gradient.
