Folding and Faulting Chapter 4, Sec. 4
Stress • Amount of force per area put on an object
Three types of stress: Compression Tension Shear
FOLDING • Rock layers bend due to stress • Assume most rocks are laid down horizontal
FAULTS • The line along which rocks break and move
Normal Faults • Caused by tension forces • Hanging wall moves down
Reverse Faults • Caused by compression forces • Hanging wall moves up
Strike-slip Faults • Opposing forces cause rock to break • Move horizontally
