What makes the wind blow?

Answer 1

Warm air rises and cold air sinks, depending on where the temperature changes occur will give you the direction of the wind. For instance, on the coast as the sun heats up the land, the air is warmer and rises, pulling cooler air from sea to replace it. This movement is wind. During the night, the land cools down, but water is fairly stable at maintaining its temperature and usually the wind will blow out to sea. This is a general example and variables will certainly cause differences.
