What does the term "karst" mean?
Karst is a type of landform that forms when soluble rocks dissolve.
A karst is a type of landform that forms when soluble rocks dissolve from interaction with groundwater or surface water. Some examples of soluble rocks include limestone, dolomite, and gypsum. An area made up of limestone or other soluble rocks will gradually dissolve and erode as it is exposed to water. Karsts may have sinkholes, towers, underground rivers, and other structures that give them their unique type of topography.
One of the most well-known karats is the South China Karst , a World Heritage Site.
