EPS C20 FINAL QUESTIONS AND ANSWERS

Name the two classes of seismic waves. - correct answer-Body waves and surface waves Name the four types of seismic waves. - correct answer-P-waves, S-waves(up and down motion, particles move up and down) , Rayleigh waves, and Love waves Which type of seismic wave has the same mechanism as an acoustic wave in the air? - correct answer-P-wave Name the two major scales by which we measure how big an earthquake is and explain their differences. - correct answer-Intensity: Determines damage and detailed observation of effects. Magnitude: Determines the energy released by an EQ Does an earthquake of magnitude 6 have the intensity "6?" - correct answer-No How much larger is a magnitude 5 earthquake compared to a magnitude 4 in terms of amplitude? - correct answer-10 times What is this factor when you compare a magnitude 4 to a magnitude 7? (think logarithms) - correct answer-4-7 = factor 1000 (10^3)
