These large pieces of rocks are called tectonic plates. Tectonic plates never stop moving, this process is called continental drift. Tectonic plates move because of convection currents. These convection currents happen in the mantle, underneath the tectonic plates. The heat, which causes the convection currents, is produced from the radioactive decay left over from the Earths formation. The reason why convection currents are relevant to the moving of tectonic plates is because the heat builds up pressure underneath the crust (tectonic plates).
