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.
Many geologists believe that the mantle flows because of convection currents. Convection currents are caused by the very hot material at the deepest part of the mantle rising, then cooling, sinking again and then heating, rising and repeating the cycle over and over.The next time you heat anything like soup or pudding in a pan you can watch the convection currents move in the liquid.hen the convection currents flow in the mantle they also move the crust. The crust gets a free ride with these currents. A conveyor belt in a factory moves boxess like the convection currents in the mantle moves the plates of the Earth.
