The power of the theory of plate tectonics lies in its ability to combine all of these observations into a single theory of how the lithosphere moves over the convecting mantle.

Advances in seismology, computer modeling, and mineralogy and crystallography at high temperatures and pressures give insights into the internal composition and structure of the Earth.

The rock cycle illustrates the relationships among them (see diagram).

Transform boundaries, such as the San Andreas Fault system, resulted in widespread powerful earthquakes.

This theory is supported by several types of observations, including seafloor spreading and the global distribution of mountain terrain and seismicity.

There is an intimate coupling between the movement of the plates on the surface and the convection of the mantle (that is, the heat transfer caused by bulk movement of molecules within fluids).
