Another medium for waves that was not discussed in this module is the earth, which vibrates in various ways due to earthquakes producing seismic waves.Research and then develop a presentation that describes these seismic waves in terms of the vocabulary you learned in this lesson, and shows how these waves demonstrates several of the wave phenomena that you have learned, such as reflection, refraction, resonance and interference.

Your presentation may include, but is not limited to:

• A comparison of P-waves and S-waves
• The discovery of the "Moho" boundary
• A discussion of earthquake energy and magnitude
• Comparison of Moment Magnitude versus Richter Scale
• The formation and propagation of tsunami waves
• The function of a seismograph

You must clearly document your sources.You may need to use resources outside of this course to finish this assignment. If so, please submit a Works Cited document. If you need assistance, visit the Developmental Module for information on citing any resources that you used.
