Across
  1. 5. type of fossil where the hollow part of the organism is filled with sediment
  2. 6. type of boundary where two plates pull apart
  3. 7. movement of fluid from a cool area to a warm area through water, air or molten rock
  4. 10. happens at a convergent boundary, one plate goes underneath the other underwater causing this
  5. 14. where two plates converge on each other; one plate slides under the other
  6. 15. type of boundary where two plates collide
  7. 17. the layering of rocks, oldest at the bottom, newest at the top
  8. 19. type of boundary where two plates slide past each other
  9. 20. name of the super continent that formed millions of years ago
  10. 21. "turning into stone" turns the hard parts of the organism and turns them into stone
Down
  1. 1. happens at a divergent boundary where plates move apart, magma comes up, hardens and turns into new ocean floor
  2. 2. type of fossil where the organisms stay in their original state or close to their original state
  3. 3. scientist who developed the idea of continental drift
  4. 4. dating of Earth's history, broken up into eons, eras, periods, epochs and ages
  5. 8. happens at a divergent boundary, low area of land between two higher areas
  6. 9. occur when hot magma pushes its way through Earth's crust
  7. 11. the study on how the plates have moved over time and have caused major landforms
  8. 12. theory of how the continents have shifted over time
  9. 13. large pieces of rock that make up the lithosphere
  10. 16. type of fossil that shows plant existence and animals movement such as, root channels, footprints, and burrows
  11. 18. type of fossil where the imprint of the organism is left
