RECOGNIZING FAULTS AND FOLDS

Do you remember your forces, faults, and folds from the introduction?

FAULTS: when rocks break due to force. Put mouse cursor in image to see what it looked like before the force was applied to it.

Normal Fault
Caused by tension
Reverse Fault
Caused by compression
Strike-Slip Fault
Caused by shear (lateral) forces

FOLDS: when rocks bend due to force.

Anticline
Caused by compression
Folded up like an "A"

Syncline
Caused by compression
Folded down like a "U"
