Across
  1. 3. the outer-most layer of the Earth where we live.
  2. 6. This mid-layer of the Earth is where Magma moves in circular currents moving the Earth's Crust
  3. 9. Special mountain where lava erupts from the crater at the top
  4. 13. one a dense plate is pushed under and melts a less dense plate
  5. 14. Dense Crust made of basalt found under the sea
  6. 15. These Circular movements of rock in the mantle are the cause of all earthquakes volcanoes and plate movement
  7. 16. Violent shaking of the Earths Crust
  8. 18. This occurs at divergent boundaries in the ocean when the ocean floor spreads apart
  9. 20. Boundary where plates separate such as during sea floor spreading
  10. 21. less dense crust made of granite found on land
  11. 22. fossils of this fresh water Crocodile found on all continents, that could not swim across the ocean prove the drift theory
Down
  1. 1. theory that explains scientifically and geologically how the plates move
  2. 2. The first piece of evidence for the drift that the coastlines fit like a
  3. 4. PLates Slide horizontally past each other
  4. 5. the super-continent that existed 250 million years ago
  5. 7. theory that states all continents were once one giant landmass that has since split apart
  6. 8. fossils of this Palm like plant were found on all continents and had to be carried there by animals
  7. 10. Boundary where plates collide creating volcanoes islands or trenches
  8. 11. Long Structure created at a divergent plate boundary
  9. 12. The deepest parts of the ocean created by a convergent boundary
  10. 17. this is a famous transform Fault that cuts through the state of California where the Pacific and North American plates meet
  11. 19. top of the mantle in which the crust floats on
