Detailed explanation-1: -Compression-the stress force that squeezes rock until it folds or breaks. Deformation-any change in the volume or shape of Earth’s crust. Fault-a break in Earth’s crust where slabs of crust slip past each other.
Detailed explanation-2: -Tensional stress (or extensional stress), which stretches rock; Compressional stress, which squeezes rock; and. Shear stress, which result in slippage and translation.
Detailed explanation-3: -Near the surface, if the stress continues, the rock will fracture (rupture) and break. [Figure 4] With increasing stress, the rock undergoes: (1) elastic deformation, (2) plastic deformation, and (3) fracture.
Detailed explanation-4: -Answer and Explanation: Folds are exposed to compression stress. Rocks deform plastically and crumble due to this stress, producing the fold.
