Across
  1. 3. this type of plate is thinner and more dense than the continental
  2. 5. the layer of the Earth we believe to be LIQUID iron and nickel
  3. 9. this type of plate is thicker and less dense than the oceanic
  4. 11. the layer of the Earth we believe to be SOLID iron and nickel
  5. 13. one tectonic plate is pushed beneath another
  6. 14. these events are common at plate boundaries and are cause by motion of plates (and sometimes magma)
  7. 17. plate boundary where the plates collide
  8. 18. another word for an earthquake wave
Down
  1. 1. another name for the crust
  2. 2. the layer of the Earth upon which the plates float
  3. 4. this is a long narrow, deep depression on the seafloor
  4. 6. point on earth's surface directly above an earthquake
  5. 7. the dividing line where 2 tectonic plates meet
  6. 8. this occurs at mid-ocean ridges where new crust is formed
  7. 10. the process in which hotter magma rises and cooler magma sinks causing the plates to move
  8. 12. plate boundary where the plates move apart
  9. 15. plate boundary where 2 plates slide past each other
  10. 16. sections of Earth's crust, can be oceanic or continental
