Surface Features:
* Sinkholes (Doline): Depressions in the ground formed by the collapse of the roof of an underground cave or by the dissolution of the bedrock.
* Uvala: Large sinkholes formed by the coalescence of smaller ones.
* Polje: Large, flat-bottomed depressions, often with fertile soil, formed by the coalescence of several uvalas.
* Caves and Caverns: Underground spaces formed by the dissolution of rock.
* Karren: Small, grooved, or pitted formations on exposed rock surfaces caused by rainwater dissolution.
* Dry Valleys: Valleys that have lost their streams due to underground drainage.
* Blind Valleys: Valleys with a stream that disappears underground.
* Tower Karst: Steep, conical, or spire-shaped hills formed by the dissolution of limestone in areas with high rainfall.
* Hum: Flat topped hills or plateau formed by the weathering of limestone.
Underground Features:
* Caves: Underground voids, often with intricate networks of passageways and chambers.
* Stalactites: Icicle-shaped formations hanging from the ceiling of caves, formed by dripping water.
* Stalagmites: Conical formations rising from the cave floor, formed by the deposition of calcium carbonate from dripping water.
* Columns: Vertical pillars formed when stalactites and stalagmites join.
* Flowstone: Sheet-like deposits of calcium carbonate that cover cave walls and floors.
Hydrological Features:
* Underground drainage systems: Water flows through a network of caves and underground channels.
* Springs: Where groundwater emerges at the surface.
* Sinkholes acting as natural drainage points: Rainwater seeps into sinkholes, contributing to underground drainage.
Other Features:
* Karst plains: Flat or gently rolling landscapes formed by the dissolution of limestone.
* Residual hills: Hills that remain after the surrounding limestone has been dissolved.
* Disappearing streams: Streams that flow into sinkholes or disappear underground.
Examples:
* Mammoth Cave National Park in Kentucky, USA
* The Karst region of Slovenia
* The Guilin region of China
Karst topography is unique and beautiful, and it's an important geological feature with significant impacts on hydrology, groundwater resources, and even human settlement patterns.
