When the Earth formed, the lighter elements floated to the surface where they cooled to form a crust. Although the first rocks were formed over 3,500 years ago, they have not stayed the same. They have been changed from forces on the inside and the outside of the Earth. The coastlines on each side of the Atlantic appear to have a jigsaw fit.

This split up to form the continents we know today.
Fact File: Movement of the land is still taking place as India and Asia are colliding, forming the Himalayas. This movement is called continental drift.
