Drifting of the large tectonic plates and the superimposed continents is not only powered by the heat-driven convection processes in the Earth's mantle, but rather retroacts on this internal driving processes. In doing so, the continents function as a thermal blanket, which leads to an accumulation of heat underneath, and which in turn can cause the break-up of the super-continents.
