If Earth’s plates were not moving, all of the ocean crust should be the same age and the rock would just build up there and form a giant mountain and eventually an island. This does not appear to be happening. Instead, new rock is being formed at the mid-ocean ridge and appears to move away from the ridge as it ages. The fact the rocks get progressively older as they move away from the ridge suggests this. Also, rocks moving is evidence for the idea that Earth’s plates are moving because Earth’s plates are made up of the crustal rocks on Earth’s surface.
