  3. 7. A downward fold in rock formed by compression in earths crust.
  4. 9. ______ vents: areas along mid ocean ridges where new life forms have been discovered; have food webs that rely on chemosynthesis
  5. 10. The point beneath earths surface where rock breaks under stress and causes an earthquake.
  6. 12. The point on earths surface directly above an earthquake focus.
  7. 14. The block of rock that forms the lower half of a fault.
  8. 17. Stress that pushes masses of rock in opposite direcions, in sideways movement.
  9. 18. ___ Wall The block of rock that forms the upper half of a fault.
  10. 20. formed at continental to continental convergent boundary
  11. 22. a device that records ground movements caused by seismic waves as they move through Earth
  12. 24. Stress that streches rock so that it becomes tinner in the middle.
  13. 26. Fault A type of fault where the hanging wall slides upward caused by compression in the crust.
Down
  1. 1. Mid Ocean ____ forms at oceanic - oceanic divergent boundaries
  2. 2. place where Earth's magma moves through the crust
  3. 3. Scale a scale that rates an earthquake's magnitude based on the size of its seismic waves
  4. 5. Scale a scale that rates earthquakes according to their intensity and how much damage they cause at a particular place
  5. 6. Fault A type of fault where rocks on either side move past each other sideways with little up-or-down motion.
  6. 7. A force that acts on rock to change its shape or voulme.
  7. 8. formed at a oceanic to continental convergent boundary; are the deepest places in the oceans
  8. 11. An upward fold in rock formed by compression of earths crust.
  9. 13. Stress that squeezes rock untill it folds or breaks.
  10. 15. type of boundary where plates are moving past each other
  11. 16. a break in the Earth's crust
  12. 19. type of boundary where plates are moving towards each other
  13. 21. energy travelling as waves passing through Earth, caused by a sudden shift along a fault line or by volcanic activity
  14. 23. type of boundary where plates are moving away from each other
  15. 25. ____ Fault A type of fault where the hanging wallslides downward caused by tension in the crust.
