How are air temperature, density, and the movement of air related?

• Warm air is less dense than cold air, so it rises to create a convection cell.

• Cold air is less dense than warm air, so it sinks to create a convection cell.

• Cold air is more dense than warm air, so it rises to create a conduction cell.
