What is an earthquake? pp. G125-G126.
*) Define earthquake.
*) Define seismic waves.
*) Define fault.
Define shear strength.
Define elastic rebound.
Define friction.
List the two reasons why rocks don’t slip continuously.
*)Define focus.
*)Define epicenter.
Define fault scarp.
Illustrate Figure 1.
*)Define primary waves (p-waves)
*)Which seismic waves are first to reach a location away from the focus?
Through which materials can primary waves travel?
Compare the speed of travel of sound through air, how much faster are p-waves through
solid rock? What is their speed?
*)Define secondary waves (s-waves)
*)Define surface wave.
*)Which waves cause the most damage? Why?
Objective:
To learn the various identifiable components of earthquakes, the types of waves
produced, their speed and type of motion, and their effects.
