Plate Tectonics—The Unifying Theory of Geology

WebMay 6, 2024 · In geology, stress is the force per unit area that is placed on a rock. Four types of stresses act on materials. Figure 1. Stress caused these rocks to fracture. A deeply buried rock is pushed down by the weight of all the material above it. Since the rock cannot move, it cannot deform. This is called confining stress.
