Which feedback occurs when increased rainfall infiltrates limestone formations containing developing stalactites?

💡 Explanation

Increased rain accelerates weathering because of increased carbonic acid formation via mineral dissolution; a positive feedback enhances the dissolution rate rather than decreases it. Therefore enhanced dissolution leads to quicker stalactite and cave system formation, rather than alternatives like impeded water.
