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. WebDefinition of Deformation. It refers to the process which affects the shape, size, or volume of an area of the crust of the earth. The type of deformation varies from the type of stress and type of rock found in a specific area of …
