The three main type of stress are : Compression, Tension, and Shear stress. Compression squeezes and shortens rock while Tension stretches and pulls rock, making it thinner. Shear stress distorts a body by pushing parts of the body in opposite directions. Sheared rock bends, twists, or breaks apart and slides past neighboring rock. So, Compression stress is the stress that forms mountains resulting from large blocks of rock squeezing together.
