Across
  1. 2. stress that causes rocks to become thin, possibly making them break apart
  2. 6. most damaging earthquake waves
  3. 8. formed with a divergent boundary
  4. 10. a break in the earth's crust
  5. 11. a small earthquake that follows the main earthquake
  6. 15. the place within Earth where earthquake waves originate
  7. 16. the point on Earth's surface directly above the focus
  8. 17. most damaging earthquake waves
  9. 19. technique using sound propogation
  10. 20. plates slide past each other
Down
  1. 1. a plate boundary where two plates move away from each other
  2. 3. a giant wave usually caused by an earthquake beneath the ocean floor
  3. 4. shaking that results from the movement of rock beneath Earth's surface
  4. 5. known as “compressional waves”
  5. 7. the movement of heat through fluids
  6. 9. the soft layer of the mantle on which the lithosphere floats
  7. 12. an earthquake caused wave in the earth
  8. 13. formed with a convergent boundary
  9. 14. a plate boundary where two plates move toward each other
  10. 18. stress that causes plates to become shorter and thicker
