  2. Earthquake Activity An American developed this scale to measure the magnitude of an earthquake. Answer Richter Scale

  3. Earthquake Activity This is the action of wet soil acting like a liquid. Answer Liquefaction

  4. Earthquake Activity These are ocean waves caused by an earthquake. Answer Tsunami or Seismic Sea Wave

  5. Earthquake Activity Seismologists use this scale to measure the intensity of an earthquake. Based on the destruction caused. Answer Mercalli Scale

  6. Earthquake Activity Name one warning sign of an impending tsunami. Answer Shoreline moves rapidly out to sea, exposing land that is usually underwater

  7. Faults This type of fault is caused by tensional forces. Answer Normal Faults

  8. Faults A reverse fault results from this type of force. Answer Compression

  9. Faults Name the three types of forces that create faults. Answer Shear, Compression, Tension

  10. Faults In this type of fault the rocks on either side move past one another with out much up or down movement. Answer Strike-Slip Fault

  11. Faults Name an example of a strike-slip fault. Answer San Andreas Fault

  12. Features of Earthquakes These are the fastest seismic waves. Answer Primary Waves

  13. Features of Earthquakes These are generated by an earthquake and travel through the earth. Answer Seismic Waves

  14. Features of Earthquakes These types of waves are the slowest and cause the most destruction. Answer Surface Waves

  15. Features of Earthquakes This type of wave causes rocks particles to move at right angles to the direction of travel. Answer Secondary Waves

  16. Features of Earthquakes These waves move rock particles in a backward, rolling motion and a side to side, swaying motion. Answer Surface Waves

  17. Earthquake Terms This is the point where the energy is just released. Answer Focus

  18. Earthquake Terms This is the point on the earth’s surface directly above the focus where surface waves radiate outward. Answer Epicenter

  19. Earthquake Terms To pin point the epicenter of an earthquake seismologists need to know the difference in arrival times of P and S waves and the location three of these. Answer Seismograph Stations

  20. Earthquake Terms Rocks will break when pressure builds up and exceeds this term. Answer Elastic Limit

  21. Earthquake Terms This is the boundary between the crust and the upper mantle. Answer Mohorivic Discontinuity or Moho

  22. MISC Vibrations produced by breaking rock Answer Earthquake

  23. MISC This is the paper record of an earthquake. Answer Seismogram

  24. MISC Seismic waves bend or stop because of changes of this Answer Density or Materials

  25. MISC The material that secondary wave cannot travel through Answer Liquid

  26. MISC Because of bending and stopping of seismic waves this area is created. AnswerShadow zones

  27. Earthquake Safety Why would securing gas appliances help make your home earthquake safe? Answer To keep them from moving a great deal during an earthquake, which would cause a less of a chance for a gas line to break and leak gas
