write the distribution of karst tropography of the world?
Answers
Answer:
Karst landscapes develop where the bedrock is comprised of an extremely soluble calcium carbonate rock, for example: limestone, gypsum, or dolomite. Limestone is the most soluble calcium carbonate rock. Consequently, most karst regions develop in areas where the bedrock is limestone.
Explanation:
Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves.[1] It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions.[2] Subterranean drainage may limit surface water, with few to no rivers or lakes. However, in regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground.
