Plate tectonics is a theory of geology. It has been developed to explain large scale motions of the Earth 's lithosphere. This theory builds on older ideas of continental drift and seafloor spreading. Dissipation of heat from the mantle is the original source of energy driving plate tectonics. Exactly how this works is still a matter of debate. The driving forces of plate motion continue to be active subjects of on-going research.
