Understanding Convection Currents

Heated air in our atmosphere expands, becoming less dense. Because it is less dense, it rises upward. Cooler air rushes in to replace the air that lifted up. As warm air rises and cool air falls, a giant circular pattern is created. Eventually the warmer air cools and begins to fall again. _(Kidsgeo.com)
