By convection currents in the mantle.


The mantle is made up of liquid magma, and it is the convection currents in this part of the Earth's crust that cause the tectonic plates to move.

The movement of the tectonic plates can change the arrangement of the continents on the Earth's surface, and depending on the length of time that the plates are allowed to move, this can drastically change the appearance of the Earth's surface.
