Which change accelerates cave formation where joints exist?

💡 Explanation

Karst landscapes feature caves created when fractures allow rainwater to react with carbon dioxide and increase the dissolution rate by acidity increase; therefore carbonic acid accelerates cave creation, rather than alternatives which would decrease reaction dynamics.

• Which mechanism leads to sinkhole formation when carbonic acid saturates limestone?
• Which event follows explosive eruptions if tephra erosion slows?
• Which outcome results when concentrated animal feeding operations (CAFOs) induce sinkhole enlargement in karst regions?
• Near large desert regions, which outcome results from subsidence within the Hadley cell?
• Which geographic outcome is accelerated by enhanced carbonic acid dissolution?
• Which consequence results when rapid aggradation overwhelms river levees?
