GEOLOGY

Detailed explanation-1: -This is called confining stress. Compression squeezes rocks together, causing rocks to fold or fracture (break) (figure 1).

Detailed explanation-2: -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-3: -There are three types of stress: compression, tension, and shear. Stress can cause strain, if it is sufficient to overcome the strength of the object that is under stress.

Detailed explanation-4: -Handily, these three senses of stress also correlate with the three types of plate boundaries. Compressive stress happens at convergent plate boundaries where two plates move toward each other. Tensional stress happens at divergent plate boundaries where two plates are moving away from each other.

Detailed explanation-5: -Compressive stress is a force that causes a material to deform to occupy a smaller volume. When a material is experiencing a compressive stress, it is said to be under compression. A high amount of compressive stress, such as tensile stress, leads to failure due to tension.
