Convection Currents
Warm air is lighter and therefore rises. Cold air holds more water and is heavier. Cold air sinks lower than warm air.
This is called convection.
Cold water sinks, hot water rises.
No, cold sinks and heat rises.
Warm air rises at the equator and cold air sinks at the poles. Warm air expands and cool air contracts and compresses.
technically hot air does not really rise it is the cold air that sinks below it because it is more dense.
Because of convection: heat rises and cold sinks
HOT rises COLD sinks
Warm air rises,and then sinks when the air is cold.
Warm air rises. Cold air sinks.
