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 currents are caused by the inner core, which is the  Inner layer of the Earth.    Convection currents begin due to the extreme heat of the inner  core.The â¦ inner core heats up the very bottom of the mantle. The  heated up substances within the mantle has a higher temperature  than those higher in the mantle and closer to the surface of the  earth.onvection currents are caused by the inner core, which is the  Inner layer of the Earth.
