  4. THE SHAKING THAT RESULTS FROM MOVEMENT OF ROCK BENEATH EARTH’S SURFACE

  5. EARTHQUAKE

  6. STRESS THAT STRETCHES ROCK SO THAT IT BECOMES THINNER IN THE MIDDLE

  7. TENSION

  8. STRESS THAT SQUEEZES ROCK UNTIL IT FOLDS OR BREAKS

  9. COMPRESSION

  10. THE BLOCK OF ROCK THAT FORMS THE LOWER HALF OF A FAULT

  11. FOOTWALL

  12. STRESS THAT PUSHES MASSES OF ROCK IN OPPOSITE DIRECTIONS, IN A SIDEWAYS MOVEMENT.

  13. SHEARING

  14. What kind of fault is this?

  15. NORMAL

  16. THE BLOCK OF ROCK THAT FORMS THE UPPER HALF OF A FAULT

  17. HANGING WALL

  18. THE POINT ON EARTH’S SURFACE DIRECTLY ABOVE AN EARTHQUAKE’S FOCUS

  19. EPICENTER

  20. A SCALE THAT RATES EARTHQUAKES ACCORDING TO THEIR INTENSITY AND HOW MUCH DAMAGE THAT CAUSE TO A PARTICULAR PLACE

  21. MERCALLI SCALE

  22. THE POINT BENEATH EARTH’S SURFACE WHERE ROCK BREAKS UNDER STRESS AND CAUSES AN EARTHQUAKE

  23. FOCUS

  24. What stress is acting on the strike-slip fault?

  25. SHEARING

  26. A TYPE OF FAULT WHERE ROCKS ON EITHER SIDE MOVE PAST EACH OTHER SIDEWAYS WITH LITTLE UP OR DOWN MOTION

  27. STRIKE-SLIPFAULT

  28. TYPE OF FAULT WHERE THE HANGING WALL SLIDES DOWNWARD; CAUSED BY TENSION IN THE CRUST

  29. NORMALFAULT

  30. A TYPE OF SEISMIC WAVE THAT COMPRESSES AND EXPANDS THE GROUND

  31. P WAVE

  32. A SCALE THAT RATES EARTHQUAKES BY ESTIMATING THE TOTAL ENERGY RELEASED BY AN EARTHQUAKE

  33. MOMENT MAGNITUDE SCALE

  34. A TYPE OF FAULT WHERE THE HANGING WALL SLIDES UPWARD; CAUSED BY COMPRESSION IN THE CRUST

  35. REVERSE FAULT

  36. A LANDFORM THAT HAS HIGH ELEVATION AND A MORE OR LESS LEVEL SURFACE

  37. PLATEAU

  38. What stress causes these two normal faults to form?

  39. TENSION

  40. A UPWARD FOLD IN ROCK FORMED BY COMPRESSION OF EARTH’S CRUST

  41. ANTICLINE

  42. A DOWNWARD FOLD IN ROCK FORMED BY COMPRESSION IN EARTH’S CRUST

  43. SYNCLINE

  44. A TYPE OF SEISMIC WAVE AHT MOVES THE GROUND UP AND DOWN OR SIDE TO SIDE

  45. S WAVE

  46. A TYPE OF SEISMIC WAVE AHT FORMS WHEN P WAVES AND S WAVES REACH EARTH’S SURFACE

  47. SURFACE WAVE

  48. What stress is acting on this part of the crust?

  49. COMPRESSION

  50. THE MEASUREMENT OF AN EARTHQUAKE’S STRENGTH BASE ON SEISMIC WAVES AND MOVEMENT ALONG FAULTS
