Karst topography describes a distinctive landscape formed by the dissolution of soluble bedrock, most commonly limestone. The chemical weathering process involves acidic water percolating through fractures and bedding planes, enlarging passages underground and dissolving the rock structure. Characteristic features of this terrain include extensive subterranean drainage systems, allowing surface water to drain quickly through sinkholes (dolines), which feed into large underground cave networks. Over time, the dissolution results in highly fractured surface rock, large underground rivers, and sometimes the formation of speleothems, such as stalactites and stalagmites, within the resulting cave systems.
