Convection currents: a cycle of which heat energy in a liquid rises to the top then becomes dense because it is farther away from the heat source at the bottom. the energy sinks to the bottom then heats up again. the cycle repeats.
This is the essential driving force behind convection currents. Water in a pot that is heating toward boiling has a convection current that is easy to understand. The top of the water is exposed to the cooler air, and when it starts to bubble then it releases even more heat.
