GEOLOGY

Detailed explanation-1: -Tension: Stress which occurs when rock pulls apart or gets longer. Shear Stress: Stress which occurs when tectonic plates move past each other causing rock to twist or change shape.

Detailed explanation-2: -This is called confining stress. Compression squeezes rocks together, causing rocks to fold or fracture (break) (figure 1). Compression is the most common stress at convergent plate boundaries. Rocks that are pulled apart are under tension.

Detailed explanation-3: -Tension is a directed (non-uniform) stress that pulls rock apart in opposite directions. The tensional (also called extensional) forces pull away from each other. Compression is a directed (non-uniform) stress that pushes rocks together. The compressional forces push towards each other.

Detailed explanation-4: -Tensional stress (or extensional stress), which stretches rock; Compressional stress, which squeezes rock; and. Shear stress, which result in slippage and translation. 28-Aug-2013
