Across
  1. 3. plates collide or come together
  2. 8. Flat, featureless part of the seafloor that can extend for thousands of miles
  3. 10. two plates slide past each other
  4. 11. Division where sunlight occure
  5. 13. Relatively flat part of the continent that sticks out underwater
  6. 14. a ring-shaped reef, island, or chain of islands formed of coral around a sunken island
  7. 15. Plates divide or move apart
  8. 16. Open ocean within the Pelagic
  9. 17. Volcano that sunk beneath ocean’s surface and top flattened from wave action
  10. 18. created when two plates slide past each other
  11. 21. zone where aphotic zone begins
  12. 23. zone where trenches occur
  13. 24. Ocean seafloor or bottom
Down
  1. 1. Without light
  2. 2. decreases the deeper you go in the ocean
  3. 4. created when a continent-continent plates collide
  4. 5. when one plate slides under another plate
  5. 6. gap located at the center of the mid-ocean ridge where the plates are pulling apart
  6. 7. Underwater mountain chain, runs through middle of the ocean created by divergent boundary
  7. 9. underwater mountain formed by volcanic activity, below sea level
  8. 12. increases the deeper you go in the ocean
  9. 13. Steeply sloping edge of a continental shelf that drops to the ocean basin
  10. 19. Deep ocean trough created when an ocean plates slide under a continental plate
  11. 20. Neritic and Oceanic (the whole ocean basin)
