A karst topography is that which composes of limestone and its associated features and structures.•Karst topography and caves develop in limestone rocks due to their solubility in dilute acidic groundwater.•The solubility of limestone in water and weak acid solutions leads to karst landscapes.•Regions overlying limestone bedrock tend to have fewer visible above-ground sources (ponds and streams), as surface water easily drains downward through joints in the limestone.•While draining, water and organic acid from the soil slowly (over thousands or millions of years) enlarges these cracks, dissolving the calcium carbonate and carrying it away in solution.•Most cave systems are through limestone bedrock.•Cooling groundwater or mixing of different groundwater will also create conditions suitable for cave formation.Karst topography occurs when the underlying bedrock is dissolved. The bedrock is made of gypsum, limestone or dolomite. This causes sinkholes and caverns to form.
