Review Tips/Study Guide

Know Earth’s Internal Layers and Corresponding Depths (front cover)

Know all CH. 11 VOCAB

Know the difference in the types of faults, the rock motions associated with each, and the forces that cause each (TABLES made in class on Wed.---see example on next pg. for help)

Know the differences in the types of seismic waves and the motions associated with each (TABLES made in class on Wed.---see example on next pg. below for help)

Know how you and city planners can create safer environments that will prevent death/destruction in case of an EQ

Know where EQs are most likely to occur (think about class presentations)

Know the different methods used to measure EQs

Do Chapter Review & Standardized Test Practice Types of Type of Type of Faults Motion Force Normal Surface moves downward Tensional forces in relation to rock below (pull rock apart) the fault surface

Reverse Rock above the surface is Compression forces forced up and over the rock (squeeze rock) below the fault surface

Strike-Slip Rocks on either side of the Shear forces fault are moving past each (push rocks past one other without much upward another) or downward movement

Types of Motion Speed Seismic Associated Waves Primary Cause rock particles to Moves the fastest, first move back and forth in to arrive at a the same direction that the seismograph station wave is traveling

Secondary Cause rock particles to Medium speed, second move at right angles to the to arrive at a direction of wave travel seismograph station

Surface Cause rock particles to Slow speed, last to move in a backward, arrive at a rolling motion and a side- seismograph station to-side, swaying motion (combine the effects of P- & S-Waves)
