answer (1 of 3): As the rock underlying the tectonic plates moves in response to the heat being transmitted. The heat causes the some of the magma to rise.

Sunken mantle re heat>process repeats. tectonic plates move because they are floating on top of the liquid mantle. The forces driving plate motions. the convection currents move the plates.
