Seismic Wave Questions

  1. Describe the differences in modes of transmission for P-, S- and surface waves. 








  2. Explain how the difference in P-wave and S-wave velocities is used by geophysicists.  








  3. Explain how P-wave shadow zones were used to establish Earth inner structure.  








  4. Explain how S-wave shadow zones were used to establish Earth inner structure.  








  5. If P- and S-waves are so useful why do we care about surface waves?
