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.
