Pangaea and Continental Drift
2
In 1915, Alfred Wegner, came up with the theory of “Continental Drift.” He believed that Earth’s crust drifted slowly on top of a liquid core. He hypothesized that Earth was one super continent that he called Pangaea. Pangaea means “All Land”
3
Wegner also proposed that Pangaea first broke into 2 large land masses, Laurasia and Gondwanaland. These two continents would continue to be broken apart over time.
4
Fossil evidence also supports this theory. Tropical plants have been found in coal deposits in Antarctica.
5
Today’s theory of Plate Tectonics is a more complete picture that includes evidence that the continents have moved and are still moving
6
Evidence for Continental Drift Go to p. 277-278 in book. Write the different clues for evidence of Pangaea. Fossil clues Widespread plant clues Climate clues Rock clues
