  1. 3. Name of the layer of the Earth where the solid crust and uppermost mantle are found
  2. 4. Type of plate that is underneath the ocean
  3. 7. Type of boundary movement where two plates slide past one another
  4. 10. Ocean-based disaster caused by an earthquake at sea
  5. 11. Type of plate that is carrying land (a continent)
  6. 13. The layer named after being "weak" because it is somewhat liquid, allowing the tectonic plates to float on top of them
  7. 15. An opening or large offset created by the separation of plates
  8. 16. Outermost solid layer of the Earth, home of the tectonic plates
  9. 17. Layer of the Earth beneath the crust but outside of the core. Mainly liquid rock.
  10. 19. Type of boundary movement where two plates move toward each other
  11. 20. A ground-shaking movement due to the movement of tectonic plates
  12. 21. Name of the proposed supercontinent that existed before today's continents drifted apart
Down
  1. 1. Name of the process that causes continental drift (happens at the bottom of the sea)
  2. 2. Geological formation that forms during sea floor spreading
  3. 5. Liquid rock that rises to the surface of the earth's crust through a volcano
  4. 6. Name of the region/border shared by two plates
  5. 8. Where one plate moves on top of another plate
  6. 9. Type of boundary movement where two plates move away from each other
  7. 12. Land-based disaster caused by an earthquake affecting the surfaces of hills/mountains
  8. 14. The point on the ground closest to the origin of an earthquake
  9. 16. Innermost layer of the Earth, which is made of iron.
  10. 18. Liquid rock from beneath the crust of the earth
