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 3. The continuous cycle of magma rising and falling in the Earth's mantle is called a Convection current. The movement of magma causes friction between the tectonic plates. This friction causes the plates to move. The movement of the plates causes events like volcanic erruptions, earthquakes and tsunamis.
