Question

what causes wind?
○ differences in air pressure
○ decreases in air temperature
○ the occurrence of the coriolis effect
○ the even heating of earth’s atmosphere

Explanation:

Wind is caused by differences in air pressure. Air moves from areas of high pressure to areas of low pressure. Decreases in air temperature alone do not directly cause wind. The Coriolis effect affects the direction of wind but is not the cause. The Earth's atmosphere is not evenly heated, and even if it were, that's not the direct cause of wind. Wind is fundamentally about air pressure differences.

Answer:

differences in air pressure
