Question

explain the setting up of convection currents in air.​

Answer 1

Explanation:

Convection currents form because a heated fluid expands, becoming less dense. The less-dense heated fluid rises away from the heat source. ... For instance, a hot radiator heats the air immediately around it. The air rises toward the ceiling, pulling cooler air down from the ceiling into the radiator to be heated.
