VI)PlateTectonics-TheoryofPangaea

•  Some scientists believe the seven continents were one super continent millions of years ago.

•  This super continent was called

Pangaea •  Prove it! Scientists use the

similarity of rock types and fossil types from different continents that date to the same age.

•  This information helps support the

theory that the continents were connected to form a super continent.
