  5. 14. When one tectonic plate is pulled underneath another moving overtop
  6. 17. Plate boundary where two plates move towards each other
  7. 18. An area where molten crust material rises to the Earth's surface to form a volcano, like Hawaii

Down
  1. 1. The placement of broken down rock material into a new location from its origin
  2. 3. Dangerous events that occur due to sudden shifts in the Earth crust and tectonic plates
  3. 4. Crustal feature formed by a transform plate boundary
  4. 5. Theory that describes how the continents drift over the Earth's mantle
