  1. 4. What process does the transform boundary use?
  2. 5. What does a continent-continent collision create?
  3. 6. ridge/ What does a divergent sea floor spreading create?
  4. 8. does a transform boundary create?
  5. 13. boundary is this <-->?
  6. 14. What process does the convergent continent continent use?
  7. 15. process is used for the convergent ocean ocean collision?
Down
  1. 1. continental/Oceanic crust more dense, so it subducts under the continental crust. What convergent boundary is this?
  2. 2. boundary is this ?
  3. 3. does a convergent oceanic-continental create?
  4. 7. boundary is this -><-?
  5. 9. valley/What does a divergent boundary continental-continental create?
  6. 10. process does the convergent oceanic continental use?
  7. 11. ocean collision/ Older denser oceanic plate us subducted downward into the mantle and a chain of volcanic islands can be formed. What convergent boundary is this?
  8. 12. continental collision/ Two continental plates collide, mountains usually form because both relatively low in density. What convergent boundary is this?
  9. 15. floor spreading/ Two ocean plates pull apart from each other. What divergent boundary is this?
  10. 16. continental/ Two plates pull apart, normal faults develop on both sides of the rift and the central blocks slide downwards; rift valley are created most of the time. What divergent boundary is this?
  11. 17. arc/What does a ocean ocean collision create?
