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: -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-3: -Stress represents the action of a force or moment on a structural member. If the force pulls the member (tension) it results in a tensile stress; if the force pushes the member (compression) it results in compressive stress. Tensile stresses stretch a member and compressive stresses squeeze a member.
Detailed explanation-4: -Compressive stress is the stress on materials that leads to a smaller volume. When compressive stress is applied to the brittle materials, these materials fracture as there is a sudden release of the stored energy. When the compressive stress is applied to the ductile materials, they compress, and there is no failure.
