Folding and Faulting
🗻 Folding:
Caused by compression forces.
Happens when rock layers bend instead of break.
Common in sedimentary rock.
Types:
Anticline: Upward fold (arch).
Syncline: Downward fold (trough).
Result: Fold mountains (e.g. Alps, Himalayas)
âš¡Faulting:
Caused when rocks break due to stress.
Types of faults:
Normal fault: Caused by tension; one block drops down.
Reverse fault: Caused by compression; one block pushed up.
Strike-slip fault: Horizontal movement (e.g. earthquakes).
Earthquakes occur along faults.
🔧 Tectonic Stress:
Tension: pulls rocks apart.
Compression: pushes rocks together.
Shear: causes sliding.
