The plate tectonics theory suggests that the outer shell of the Earth's surface is
split into a few plates that move along the mantle, forming a hard shell, with ...
Exactly what drives plate tectonics is not known. One theory is that convection
within the Earth's mantle pushes the plates, in much the same way that air heated
