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.
