How does the sun contribute to the movement of air?

convection process

Heat from the sun is not captured and held in one location. Heat is distributed by convection, the transfer of heat from one place to another. Because they are lighter than cool gases and liquids, warm gases and liquids tend to rise. The heavier ones sink and displace the lighter ones. This change, or movement, of air is called winds and the change of water is known as a current. Warm air and warm water both flow from the Equator towards the North and South poles.

You may be wondering how the sun powers the wind. Without the sun, we would have no wind, as the sun heats up our air. Depending upon the earth's rotation, different parts of the earth are closer to the sun, so different areas of the earth will have warmer air. These warmer parts of the earth have warmer air, and warmer air rises. This causes the cooler air from the surrounding areas to replace the warmer air that is rising. This creates the wind that you feel on a breezy day. The wind can be small in a certain region, such as local cumulus clouds, or large cycles in the troposphere, covering large sections of the earth.
