  "id": "MLC-T-ENV-015125",
  "term": "Karst",
  "field": "Environment",
  "definition": "1. Any region underlain by limestone and characterized by a set of landforms resulting largely from the action of carbonation or other processes.\n\n2. Areas with shallow ground water, caverns, and sinkholes.\n\n3. A landscape influenced by the dissolving of limestone or gypsum; usually characterized by caves, sinkholes, and underground drainage.\n\n4. A geologic formation of irregular limestone deposits with sinks, underground streams, and caverns.\n\n5. The term \"karst\" refers to a type of topography that is formed over limestone, dolomite or gypsum by solution of the rock and is characterized by closed depressions or sinkholes, caves and underground drainage.\n\n6. Topographic area which has been created by the dissolution of carbonate rock terrain. It is characterized by caverns, sinkholes, and the absence of surface streams.\n\n7. A type of terrain where there are numerous sinkholes and large voids such as caves. Karst is created when water dissolves rocks such as limestone, halite (salt) and gypsum.\n\n8. Terrain with characteristics of relief and drainage arising from a high degree of rock solubility in natural waters. The majority of karst occurs in limestones, but karst may also form in dolomite, gypsum, and salt deposits. Features associated with karst terrains typically include irregular topography, sinkholes, vertical shafts, abrupt ridges, caverns, abundant springs, and/or disappearing streams. Karst aquifers are associated with karst terrain.\n\n9. Type of terrain where there are numerous sinkholes and large voids such as caves. Karst is created when water dissolves rocks such as limestone, halite (salt) and gypsum.\n\n10. A kind of terrain with characteristics of relief and drainage arising from a high degree of rock solubility. The majority of karst conditions occur in limestone areas, but karst may also occur in areas of dolomite, gypsum, or salt deposits. Features associated with karst terrain may include irregular topography, abrupt ridges, sinkholes, caverns, abundant springs, disappearing streams, and the lack of a well - developed surface drainage system of tributaries and streams.",
