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