Wind Is Moving Air — Like water, Air Is a Fluid too

Air is made of tiny pieces called molecules. Temperature effects the density of air: Density is how tightly packed molecules are in a substance. When air gets warm, the molecules move faster and spread out. The air becomes lighter or less dense. When air gets cold, the molecules slow down and move closer together. The air becomes heavier or more dense
