Across
  1. 5. lithosphere broken into sections that move
  2. 6. when all the continentals were one making a super continent
  3. 7. 1 continental and oceanic plates colliding
  4. 11. originator of continental drift hypothesis
  5. 14. When two plates collide or converge
  6. 15. divergent convergent and transform are know as
  7. 16. Plastic layer below the lithosphere
  8. 18. A place where folded and thrust faulted mountains form

  10. 20. 2 continental plates colliding
Down
  1. 1. where the less dense plate slides under the more dense plate
  2. 2. found below the continent
  3. 3. plates sliding past each other causing earthquakes
  4. 4. 2 oceanic plates colliding
  5. 8. heat rising and cooling causing it to sink and reheat again causing it to rise
  6. 9. found below the ocean
  7. 10. caused when 2 plates slide past each other
  8. 12. sea floor spreading
