GEOLOGY

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: -Compression: Stress which causes rock to squeeze or push against other rock. Tension: Stress which occurs when rock pulls apart or gets longer.

Detailed explanation-3: -Types of Stress 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 colliding, or where they are being buried beneath other rocks.

Detailed explanation-4: -Compressional stress is when a rock is pressed together into itself, like when crust movements cause two rocks to squeeze another one between them. Another example is when mountains are formed at a convergent boundary, like the Rocky Mountains.

Detailed explanation-5: -Compression is a directed (non-uniform) stress that pushes rocks together. The compressional forces push towards each other. Shear is a directed (non-uniform) stress that pushes one side of a body of rock in one direction, and the opposite side of the body of rock in the opposite direction.
