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 in Earth. In Earthâs mantle, large amounts of heat are transferred by convection currents, as shown in Figure 10. Heat from the core and the mantle itself causes convection currents in the mantle. Mantle Convection. d. Figure 10Mantle Convection Most geologists think that convection currents rise and sink through the mantle.
