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.
convection current. The heating and cooling of the ï¬uid, changes in the ï¬uidâs density, and the force of gravity combine to set convection currents in motion. Convection currents continue as long as heat is added to the ï¬uid. Convection currents ï¬ow in the mantle. The heat source for these currents is heat from Earthâs core and from the mantle itself. Hot columns of mantle material rise slowly.
