Karst Topography Definition Geology

Limestone, also known as chalk or calcium carbonate, is a soft rock that dissolves in water. The northeast area of the gulf of trieste in slovenia is covered with limestones. Subterranean drainage may limit surface water, with few to no rivers or lakes.

A valley excavated in limestone or formed by collapse of the roof of a cave and subsequently submerged by a rise in sea level. The term karst describes a distinctive topography that indicates dissolution (also called chemical solution) of underlying soluble rocks by surface water or groundwater. The most remarkable feature of karst regionsis the formation of caves.

In geology, the term karst topography is used to describe areas similar to that found in kras.

Karst terrain is created from the dissolution of soluble rocks, principally limestone and dolomite. The experts stated that karst is a terrain or landscape that has a special hydrological cycle as a result of the development of carbonate rocks (limestone and soluble rocks which have a good secondary porosity). Karst is a special type of landscape that is formed by the dissolution of soluble rocks, including limestone and dolomite. Karst has unique hydrology condition, this condition is caused of karst composed of soluble lithology and the lithology has good condition in secondary porosity.
