Plate Tectonics and Geologic Features

What causes the Earth's crustal plates to move?

• revolution of the Earth around the Sun

• convection currents in the Earth's mantle

• volcanism within the Earth's lithosphere

• the rotation of the Earth on its axis

Which statement is true according to the theory of plate tectonics?

• Lithospheric plates are destroyed at the mid-ocean ridges.

• Continents drift because they rest on lithospheric plates that move.

• Lithospheric plates move because the inner core of the Earth is liquid.

• Transform boundaries form when two lithospheric plates collide.

Which statement describes the geologic processes taking place at a subduction zone?

• A less dense oceanic plate slides on top of a more dense continental plate creating some new crust.

• A less dense continental plate slides on top of a more dense oceanic plate creating some new crust.

• A more dense continental plate slides under a less dense oceanic plate destroying some crust.
