Continental drift takes place because continents sit on crustal plates which float on the Earth's magma, and the magma has convection currents in it which push against the plates and cause them to move, slowly but inexorably.
The Earthâs crust and upper part of the mantle is broken into large pieces of rock. 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.
