These landscapes evolve primarily through chemical weathering caused by slightly acidic rainwater dissolving calcium carbonate over long geological periods. The result is a terrain marked by underground drainage, limited surface rivers, and distinctive surface and subsurface features. Karst regions occupy significant portions of Earth\u2019s land surface and play a crucial role in groundwater storage, cave systems, and mineral deposition, making them geomorphologically and hydrologically important.<\/span><\/p>\n<h2><b>Karst Landforms<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Karst Landforms refer to a unique geomorphic system shaped by rock dissolution, underground water movement, and structural weaknesses in carbonate rocks. These landforms are best developed in dense, thinly bedded, and fractured limestone where groundwater flow is concentrated along joints. Karst landscapes are globally distributed and support extensive cave networks, sinkholes, underground rivers, and springs. Their evolution depends on rock type, rainfall intensity, relief, and water table depth, creating highly specialized surface and subsurface morphology.<\/span><\/p>\n<p><strong>Also Read: <a
