Definitions:

Differential Stress

Stress applied to a rock body in different directions, leading to deformation like folding, faulting, or flowing.

Confining Pressure

The pressure applied equally in all directions on a rock or sediment layer, often increasing with depth in the Earth's crust.

Fluid Pressure

The pressure exerted by a fluid at equilibrium at any given point within the fluid, due to the force of gravity.

Columnar Joints

A geological feature where certain types of volcanic or igneous rock cool and shrink, forming vertical, polygonal columns of rock.
