What you need to know
- The Earth's rigid outer shell is broken into large plates that move a few centimetres a year.
- Heat from inside the Earth sets up slow movement in the mantle beneath the plates.
- Dense ocean plate sinking into the mantle helps pull the rest of the plate along.
- New crust forms where plates move apart and old crust is destroyed where they meet.
