How do limestone caves and sinkholes form in karst landscapes?
Quick Answer
Slightly acidic water dissolves soluble rock like limestone, creating underground voids and sometimes sudden collapses.
The Full Story
Karst landscapes develop where water can dissolve rock, especially limestone, dolomite, or gypsum. Rainwater picks up carbon dioxide from soil and becomes weakly acidic, allowing it to slowly enlarge cracks, conduits, and caves. If a roof above a cavity becomes unstable, the ground may collapse and form a sinkhole. Florida, the Yucatán Peninsula, and parts of China have extensive karst terrain shaped by this long-term chemical weathering.
Key Facts
1.Karst forms by dissolving soluble rock
2.Sinkholes can form when cave roofs collapse
3.Rainwater becomes weakly acidic from carbon dioxide
