Which long-term outcome results when elevated atmospheric carbon dissolves into groundwater percolating through karst landscapes?

💡 Explanation

Carbon dioxide dissolution forms carbonic acid, accelerating chemical weathering via carbonic acid dissolution, causing increased rates of cavern and sinkhole formation; therefore, option A is correct, rather than B/C/D which rely on physical processes.
