5. - a large mountain range below the ocean-bigger than any on land
6. - a huge piece of the crust (rock) that moves because of convection currents.

12. - the rising, spreading and sinking of molten material, in a circular motion in the mantle, which causes the plates to move
13. - energy from an earthquake that travels as vibrations
