Plate Tectonics

The movement of the tectonic plates is caused by

• the rotation of the Earth.

• convection currents in the Asthenosphere

• the gravity of the iron-nickel core.

• the Moho discontinuity.

What is the source of energy that drives plate movement?

• the subducton of the sea floor

• the different densities of the oceanic and crustal plates
