How do streams in limestone regions suddently disappear?
Answers
Answer:its a common lime stone feature
Explanation:They are formed when joints or fissures in the rock are enlarged by carbonation or when the roof of an underground cavern collapses. Sometimes a river or stream may “disappear” down a sink hole and continue flowing underground.
Answer:
Limestone dissolves under the action of rainwater and groundwater charged with H2CO3 (carbonic acid) and naturally occurring organic acids. The dissolution process produces a distinctive landform known as karst, characterized by sinkholes, and underground drainage.
Explanation:
rocks, principally limestone and dolomite. Karst areas are characterized by distinctive landforms (like springs, caves, sinkholes) and a unique hydrogeology that results in aquifers that are highly productive but extremely vulnerable to contamination
