Across
  1. 2. Crust:Crust that's part of continents
  2. 5. pieces of earths crust that move due to convection
  3. 6. rises and new crust is formed
  4. 9. Scale:Measures how strong the earthquake is.
  5. 10. floor spreading:when two oceanic plates pull apart,
  6. 11. currents occur in it. It is solid and hot.
  7. 14. arc:a chain of volcanic mountains formed at an ocean-continental convergent boundary
  8. 15. in crust. plates slip past each other.
  9. 17. of Plate Tectonics:Theory that plates that move
  10. 18. Crust:Dense crust below the ocean.Earths crust located under the ocean
Down
  1. 1. range:formed at a continental-continental convergent boundary
  2. 3. formed at a subduction zone.
  3. 4. to convection currents
  4. 6. Atlantic Ridge:divergent boundary in the middle of the Atlantic Ocean
  5. 7. Tectonics:Theory that crust is broken into plates and move around.
  6. 8. oceanic crust meets continental crust,
  7. 12. currents:circular movement of a substance dueto changes in temperature and density
  8. 13. arc:a chain of volcanic islands formed at an ocean-ocean convergent boundary
  9. 16. oceanic crust goes under and melts in the mantle.
