• tectonic plates move apart.

Divergent plates form which type of rocks?

• igneous 
• sedimentary

The convection currents that cause the plates to move is caused by

• temperature differences in the mantle.
• the gravitational pull of the moon.
• strong winds.
• Earth's magnetic field.

The movement of tectonic plates is believed to be caused by

• the rotation of the Earth.
• the gravitational pull of the Moon.
• strong winds.
• convection currents in the mantle.

When plates subduct

• one plate slides beneath another plate.
• the plates slide next to each other
• the plates meet at the fault line.
• the plates pull apart.
