Front

What is Pangaea?

Back

A supercontinent that existed during the late Paleozoic and early Mesozoic eras.

Front

What type of evidence did Wegener use to support his hypothesis?

Back

Fossil evidence, geological similarities, and climate evidence.

Front

What is the significance of matching rock types in different continents?

Back

It suggests that these continents were once connected.

Front

What role do fossils play in the theory of continental drift?

Back

Fossils of the same species found on different continents indicate they were once joined.
