Karst topography is a unique geographical landform shaped by the solubility of carbonate rocks like limestone or dolomite. On a Karst Plain, surface water is scarce because the drainage is primarily subterranean. Over time, the chemical dissolution of the rock creates circular depressions called sinkholes. Rivers often flow into these depressions and continue their course through vast underground cavern systems. These plains are geographically challenging for human settlement due to the lack of surface water and the risk of ground collapse, but they are critical for groundwater storage and are often sites of spectacular natural beauty and tourism.
