Convection, driven by the release of heat from the Earth's mantle. Like a pot of vegetable soup on the stove. The vegetables on the surface move around. Some are subducted and others surface.

It's the convection currents of magma flowing beneath the crust that make it move......so I'd go with d.

D. But I also believe it has something to do with Oprah Winfrey's wildly fluctuating weight.
