Understanding crustal deformation helps explain the forces necessary to bend and fold rocks like those shown above which help create mountains. This section will discuss the types of forces needed to accomplish such a powerful feat. Have you ever wondered how strong those forces would have to be? The answer to that is beyond our comprehension.
- Reading: Stress in Earth's Crust
- Enormous slabs of lithosphere move unevenly over the planet’s spherical surface, resulting in earthquakes. This chapter deals with two types of geological activity that occur because of plate tectonics: mountain building and earthquakes. First, we will consider what can happen to rocks when they are exposed to stress.
