In general, a typical karst landscape forms when much of the water falling on the surface interacts with and enters the subsurface through cracks, fractures, and holes that have been dissolved into the bedrock.
The landforms result mostly from chemical weathering of the host rock and the progressive integration of subsurface cavities, though collapse into solution cavities can also be important. Karst landscapes are often dominated by underground drainage networks that interrupt and capture surface water flow.

Frequently Asked Questions
What type of weathering causes the features of the karst landscape?
Karst topography refers to natural features produced on a land surface due to the chemical weathering or slow dissolving of limestone, dolostone, marble, or evaporite deposits such as halite and gypsum. The chemical weathering agent is slightly acidic groundwater that begins as rainwater.
Is karst a landscape?
Karst is a type of landscape where the dissolving of the bedrock has created sinkholes, sinking streams, caves, springs, and other characteristic features. Karst is associated with soluble rock types such as limestone, marble, and gypsum.
How are karst landscapes formed and how are they formed?
Karst landforms are formed due to chemical weathering of rocks over the time. The most impacted rock is the limestone which dissloves when in contact with water/ acid.
Why are karst regions important to the environment?
Karst is a special type of landscape that is formed by the dissolution of soluble rocks, including limestone and dolomite. Karst regions contain aquifers that are capable of providing large supplies of water.
Why are sinkholes common in karst landforms?
Soluble rock layers below the ground can be exposed to running water and collapse to form sinkholes and other changes in the landscape. Many karst effects like these occur due to a very high water table and underground moving water.
What kind of problems are associated with karst topography?
Karst, terrain usually characterized by barren, rocky ground, caves, sinkholes, underground rivers, and the absence of surface streams and lakes. It results from the excavating effects of underground water on massive soluble limestone. Moreover, what kind of problems are associated with karst topography?
