NettetTypes of Stress. Stresses fall into two categories: normal stress acts at right angles to a surface, and shear stress acts parallel to a surface (Figure 13.2). Normal stress is subdivided into compression, when the stresses are squeezing a rock, and tension, when stress is pulling it apart. Rocks undergo compression in regions where plates are ... NettetDifferent processes can deform rocks, the deformation is almost always the result of stress. This stress leads to the formation of fault and fold structures, both can either extend or shorten of the Earth's crust. Thick-skinned deformation specifically affects deep crystalline rock of the basement and may extend deeper into the lower crust.

NettetThe forces that cause deformation Tensional Stress (crust stretching) caused by rocks being pulled in opposite directions Compression Stress (crust shortening) squeezes rocks together till it folds or break Shear Stress (crust displacement) Causes a body of rock to be distorted side-to-side Hooke's Law NettetAs rocks are stressed, they go through stages of deformation. At first, the rock is strained enough that its shape or size may change, but the change is reversible.
