CONTINENTAL DRIFT

Some continents fit together almost perfectly, e.g. South America and Africa.

Similar fossils can be found on different continents. This shows these regions were once very close or joined together.

EVIDENCE FOR CONTINENTAL DRIFT

It was not until the 1960s that the theory of continental drift became accepted by the scientific community.

Almost identical patterns of rock layers on different continents is evidence that the rocks were once close together or joined.

Why are the continents moving?
