rise because of it's density
Warm air rises at the equator and cold air sinks at the poles. Warm air expands and cool air contracts and compresses.
Warm air molecules are fast moving and therefore less dense than cold air molecules. Since cold air is more dense (more slowly moving) it sinks.
Convection current
Warm air rises, and cool air sinks.
Warm air is less dense than cold air... therefore colder air sinks, while warm air rises.
Warm air rises,and then sinks when the air is cold.

Well, warm air rises and cool air sinks! Your welcome! :) <3
convection and subsidence
Warm air rises. Cold air sinks.
warm air rises cold air goes down sinks

whay is it
