  1. Earthquakes

  2. 1. What is the name of the instrument that records earthquake waves? • Seismograph • Seismogram

  3. Seismograph

  4. 2. What type of plate motion is it when 2 plates move away from each other, causing weak, shallow earthquakes? • Divergent • Convergent • Transform

  5. Divergent

  6. 3. What type of plate motion is it when 2 plates move toward or into each other, causing strong, deep earthquakes? • Divergent • Convergent • Transform

  7. Convergent

  8. 4. What type of plate motion is it when 2 plates slide past each other, causing shallow, moderate earthquakes? • Divergent • Convergent • Transform

  9. Transform

  10. 5. The picture of the seismic waves recorded are called? • Seismograph • Seismogram

  11. Seismogram

  12. 6. Which part of the earthquake can be located far below the earth’s surface? • Epicenter • Focus

  13. Focus

  14. 7. What do you call sections of a fault that have very little earthquake activity? • Plastic rebound • Elastic rebound • Seismic gap

  15. Seismic Gap

  16. 8. What type of gas and water lines are being used in areas where earthquakes are likely to occur?

  17. Flexible pipes, like a bendy straw.

  18. 9. The bending of rock is also called • Deformation • Moho • Shadow zone

  19. Deformation

  20. 10. Where do the strongest earthquakes usually occur? • At divergent boundaries • At transform boundaries • At convergent boundaries

  21. At convergent plate boundaries

  22. 11. Where should you go if you are in a building when an earthquake occurs? • Outside • Into the hallway • Under a piece of furniture

  23. Under a table or any furniture in the middle of the room.

  24. 12. Where are most strike-slip faults located? • At divergent boundaries • At transform boundaries • At convergent boundaries

  25. Along transform boundaries

  26. 13. What are the characteristics of “P” or Primary waves? • They can travel through solids, liquids, and gases. • They can’t travel through liquid • They travel the fastest and arrive first • They travel fast but arrive second after “S” waves.

  27. P waves are the fastest, they arrive first, they can travel through solids, liquids, and gas.

  28. 14. What causes the ground to move during an earthquake? • Plastic deformation • Elastic rebound • Stress • Tectonic force

  29. Elastic Rebound

  30. 15. What do Seismologists study? • Volcanoes • Earthquakes ( Seismic waves)

  31. Earthquakes

  32. 16. Body waves are the two fastest seismic waves they include..... • P waves (primary) • S waves (secondary) • Surface waves

  33. S & P waves

  34. 17. These waves travel slower and cause the most damage. • P waves • S waves • Surface waves

  35. Surface waves

  36. 18. The actual point down in the earth where the rocks shift and start an earthquake is called….. • Epicenter • Moho • Shadow zone • Focus

  37. The focus

  38. 19. This is located directly above the focus, it is the point on the surface of the earth where the earthquake occurred. • Epicenter • Moho • Shadow zone • Focus

  39. Epicenter

  40. 20. When rock is _________, energy builds up in it. Seismic waves occur as this energy is __________.

  41. Elastically deformed, released.

  42. 21. If you are outside when an earthquake begins to occur what should you do?

  43. Lie face down away from buildings.

  44. 22. If the S waves arrive a long time after the P waves this tells you that the earthquake is probably: • Close to the seismograph • Far away from the seismograph

  45. Far away from the seismograph.

  46. 23. Where do most earthquakes usually occur? • Along the edges of the earth’s continents • Along the edges of the earth’s oceans • Along the edges of the earth’s tectonic plates

  47. Along the edges of the earth’s tectonic plates.

  48. 24. A scientist that studies earthquakes is called a • Volcanologist • Seismologist • Biologist

  49. Seismologist

  50. 25. Giant masses of the earth’s crust that make up the outermost part of the crust are called:
