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.
However, in conduction the heat is transferred from one molecule to another, whereas in convection the heated fluid itself is actually moving. As it does, it removes or displaces cold air in its path. The flow of heated fluid in this situation is called a convection current.
