Ch 5- Changing the Crust

The rising and falling of the lithosphere into the asthenosphere due to changes in weight are called isostatic adjustments.

These movements cause stress on the crustal rocks

Many times the rocks will fold without breaking; 3 ways

1. Anticline

2. Syncline

3. Monocline

Other times the rock will break; if the rocks do not move it is called a fracture

If the rocks move, it is called faulting

Normal fault

Reverse fault

Thrust fault

Strike-slip fault

Constant changing of the crust forms mountains and valleys

Types of mountains

1. Folded mountains

2. Plateaus

3. Fault-block mountains

4. Volcanic mountains

5. Dome mountains
