Across
  1. 3. travel in all directions from the focus through the body of the Earth inner layers (core, mantle, crust).
  2. 6. Pushes a mass of rock in tow opposite directions
  3. 8. A change in the shape of a rock caused by stress; there are two
  4. 10. Two blocks of rock are pushed together by compression (convergent boundary)
  5. 11. point on the surface directly above the focus
  6. 12. Change in rock that is NOT permanent; when stress is removed rock goes back to original shape
  7. 14. Two blocks of rock slide horizontally past each other in opposite directions caused by SHEAR stress.
  8. 15. Two blocks of rock are pushed together by compression (convergent boundary)
  9. 17. tension causes oceanic crust to spread allowing hot rock from mantle to rise creating high ridges
  10. 19. collision between two continental plates
  11. 23. creates a permanent change in the shape of a rock; usually occurs when rocks are weak or hot
  12. 24. Waves that carry energy of an earthquake away from the focus; there are three types
  13. 25. Two blocks are pulled apart by tension (divergent plate boundary)
  14. 27. Do not travel through the Earth but instead they are constrained to travel along the surface of the Earth only from the epicenter(outer crust).
  15. 29. the location under the Earth where the earthquake actually originated
Down
  1. 1. curved line of volcanoes that forms parallel to plate boundaries
  2. 2. Two blocks are pulled apart by tension (divergent plate boundary)
  3. 4. one plate goes under another during collision forming a deep trenches where the two plates meet
  4. 5. a slow wave that moves like ripples in a pond causing much damage.
  5. 7. an area of many fractured pieces of crust along a large fault
  6. 8. Two blocks of rock slide horizontally past each other in opposite directions caused by SHEAR stress.
  7. 9. a high temperature
  8. 13. divided into several plates that glide over the plastic-like and less rigid asthenosphere (upper mantle).
  9. 16. when divergent boundaries occur within a continent, they cause enormous splits in the crust
  10. 18. Squeezes rock until it folds or breaks
  11. 20. Sudden release of energy in the earths crust that causes vibrations in the ground
  12. 21. A natural break or crack in the rocks that make up earth’s crust, along which rocks have moved relative to one another.
  13. 22. Vibrates forward and backward in the direction of the wave AND vibrates up and down perpendicular to the direction of the wave.
  14. 26. Pulls on the crust, stretching rock so it becomes thinner in the middle
  15. 28. A force that acts on rock to change its shape or volume
