Yeah, So as heat rises ( as its less dense), it goes higher. As it does, it pushes the cold air (at the top) to the bottom.
After a moment, the hot air at the top loses heat and the cold air (now at the bottom) gains heat. The 'now' hot air, at the bottom, rises to the top and pushes the 'now' cold air back down. This cycle repeats, and is known as convection currents.
