GEOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -Shearing Stress that pushes a mass of rock in two opposite. directions is called shearing. Shearing can cause rock to break and slip apart or to change its shape.

Detailed explanation-3: -Compression: Stress which causes rock to squeeze or push against other rock. 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-4: -shear stress, force tending to cause deformation of a material by slippage along a plane or planes parallel to the imposed stress. The resultant shear is of great importance in nature, being intimately related to the downslope movement of earth materials and to earthquakes.

Detailed explanation-5: -In physics, stress is the force acting on the unit area of a material. The effect of stress on a body is named as strain.
