What are some basic features associated with Karst topography?
Karst features take many thousands of years to form. The slow dissolving action starts as rain falls through the atmosphere, picking up CO2. The CO2 and H2O chemically react to form a weak acid called carbonic acid. This is the same acid that makes carbonated drinks taste tangy. The acidic rain water leaches down through the soil into fractures in the bedrock. The carbonic acid in the moving ground water slowly dissolves the bedrock forming passageways and caves. This geological process results in unusual surface and subsurface features ranging from SINKHOLES, DISAPPEARING STREAMS and SPRINGS TO COMPLEX CAVE SYSTEMS. The most widely distributed karst landscapes are dolines, commonly called SINKHOLES. Sinkholes are surface depressions formed by either the dissolution of bedrock for a bowl shaped depression or the collapse of shallow caves. Sinkholes can range in size from a few feet to over 300 feet deep and several feet to thousands of feet wide. Sinkholes may fill up with water becoming ponds or lakes. The most popular karst feature is caves. Karst topography forms the longest cave system, the Mammoth Cave. This Kentucky cave is over 350 miles long. Alabama where Karst topography is prevalent boasts over two thousand caves. Many unique features are found in Karst caves. Stalactites (those features that hang from the ceilings of caves) and stalagmites (those features that rise from the floor of the cave) are formed by the deposition of slowly dripping calcium carbonate solutions.
For the best answers, search on this site shorturl.im/avyHz all can be found in areas of karst topography it is a poorly wriiten question however c.flowing rivers, can be found in areas away from karst topography as well, so it is the best answer
Karst topography is a landscape shaped by the dissolution of a layer or layers of soluble bedrock, usually carbonate rock such as limestone or dolomite. Due to subterranean drainage, there may be very limited surface water, even to the absence of all rivers and lakes. Many karst regions display distinctive surface features, with sinkholes or dolines being the most common. However, distinctive karst surface features may be completely absent where the soluble rock is mantled, such as by glacial debris, or confined by a superimposed non-soluble rock strata. Some karst regions include thousands of caves, even though evidence of caves that are big enough for human exploration is not a required characteristic of karst. I hope this is helpful.
