Which geological outcome results from prolonged carbonic acid dissolution in karst caves?

💡 Explanation

Increased connectivity in response to carbonic acid weathering of limestone is observed, because the dissolution enlarges passages and joints—a process called chemical weathering—therefore expanding the network, rather than increasing deposition, seismic activity, or mineral oxidation.
