Fracturing of rock resulting in parallel displacement relative to each side along the fault zone. Faults easily act as conduits for groundwater. Interbedding is also known as interstratification. A series of regular breaks in a rock formation. Jointing may be caused by stress or the release of pressure or chemical and temperature changes.
Joints provide an easy pathway for groundwater movement.
A structure formed inside rock that has been dissolved by groundwater. The types of rock that karst generally occurs in are limestone, dolomite and gypsum. A common example of a karst feature is an underground cave. Karst topography is the visible expression on top of the ground, of karst features below the ground. Karst topography is visible around the Mammoth Cave area of Kentucky.
