5 Written Questions

1. moderate and shallow earthquakes occur here
2. move ground up and down in circles; slowest; most destructive; feels like a roller coaster
3. compares the distance between P waves and S waves
4. this causes earthquakes; the ground suddenly retains original shape
5. the common method used to find an earthquake's epicenter

5 Matching Questions

1. base isolators
2. earthquake hazard
3. epicenter
4. marsquakes
5. body waves

1. a measures how vulnerable an area is to future earthquakes
2. b seismic waves that travel through the Earth's interior
3. c some earthquakes, though seismographs often acted more like a wind gauge because of the wind
4. d these are in the base of the building; made of rubber w/ a lead core; absorb seismic waves to avert their travel through the building

5 True/False Question

1. seismology → a recording of the shaking motion in earthquakes
   

   True        False

2. shadow zone → seismic waves travel much faster upon reaching this area
   

   True        False

3. seismograph → an instrument that records seismic waves
   

   True        False

4. mass damper → some earthquakes, though seismographs often acted more like a wind gauge because of the wind
   

   True        False

5. sunquakes → caused by solar flares; much stronger than our earthquakes
   

   True        False
