  12. 21. the transfer thermal energy by the movement of molecules in air or liquid from one place to another
  13. 22. a theory that the middle of the ocean is spreading apart, forming new oceanic crust
  14. 23. a large layer of solid rock that covers part of the Earth's surface
  15. 26. a series of underwater Mountains that formed as a result of tectonic plates moving apart and allowing magma to rise to the surface
  16. 28. when the plates collide and cause the ground to shake vigorously
  17. 30. the movement of one tectonic plate under another tectonic plate
Down
  1. 1. the crust in the ocean
  2. 3. the theory that the surface of the Earth is divided into a series of plates that are continually moving
  3. 5. the geologist which discovered the plate tectonics theory
  4. 6. a place in the mantle where it melts rock into magma
  5. 7. underwater cliffs between the beach and the ocean
