Convection currents are the transfer of heat through the Earth's magma. They can be found in the mantle. The hottest part of the Earth is the core. the heat from the core is transferred into the lower mantle.
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.
