Seismic Waves (PS3D) Practice

I can explain how to use EQ wave characteristics as tools of geologic discovery.

  1. Explain how the difference in P-wave and S-wave velocities is used by geophysicists.
  2. Explain how P-wave shadow zones were used to establish Earth inner structure.
  3. Explain how S-wave shadow zones were used to establish Earth inner structure.
  4. Explain how earthquakes were used to determine plate boundaries
  5. How would plotting earthquake depths have helped geophysicists when they were first trying to understand oceanic-continental convergent plate boundaries? Remember they didn't have the cross-section drawings of boundaries we have seen.
  6. The video we watched about Pacific Northwest earthquakes said there were three locations for earthquakes here: subduction, deep focus (or Benioff) and crustal earthquakes. Draw our subduction zone cross-section diagram showing those locations.
