  1. Warm Up September 10th, 2013 3 Observations, 3 Inferences, 1 Question So (second chance) how did the Earth form?

  2. Theory of Continental Drift* The 7 major continents were once all part of one piece of land (a supercontinent) called Pangaea. Over a long period of time (millions of years), the plates on the lithosphere were shifted apart from each other.

  3. Evidence of Continental Drift* Fossils – Similar fossils found on different continents. Climate – Climate change shows tropical plants in Greenland and glacial streaks in South Africa. Rocks – Similar rocks and formations on different continents.

  7. Continental and Oceanic Crust

  8. When plates come together. Convergent Boundary*

  9. When plates pull apart. Divergent Boundary*

  10. When plates slide past each other. Transform Boundary*
