Alfred Wegener Theory of Continental Drift –Continents formed a single landmass –Broke-up and drifted to current location Explanation for similar fossils in different parts of the world http://pubs.usgs.gov/publications/graphics/Fig2-5globes.gif
“All Earth” Pangaea Existed 245 million years ago Split into two large continents (Laurasia and Gondwana) 180 million years ago Split again into the landmasses we have today 65 million years ago
Mid-Ocean Ridges Sea-floor spreading-places where new oceanic lithosphere forms Magnetic Reversal-Earth’s magnetic poles change places
Color the major plates Cut out the plates Label the fossils from table Fit the pieces together to make Your Pangaea Glue Pangaea together
