  3. 10. Underwater mountains formed by seafloor spreading at divergent plate boundaries
  4. 11. Molten rock
  5. 12. This occurs at divergent boundaries
Down
  1. 1. This is the energy released during an earthquake
  2. 2. This is formed when one plate is pushed under the other one
  3. 3. Type of plate boundary where the plates move away from each other
  4. 6. Type of plate boundary where the plates slide past each other in different directions
  5. 7. This is what scientists use to measure earthquakes magnitude
  6. 8. Type of plate boundary where the plates move toward each other
  7. 9. This is caused by earthquakes which happen because of transform boundaries
