4. This illustration shows how heat can move
through the atmosphere as air circulates. What
causes the circulation of air?
Air in the atmosphere is heated by the Sun and
sinks to the ground.
The ground is heated by the Sun and then heats
the air, causing the air to rise.
Air loses heat to the ground and then rises
upward to obtain more energy.
The Sun heats the clouds which forces the cooler
air to move away and sink.
