Which environmental effect increases when groundwater's carbonic acid concentration diminishes within karst formations?

💡 Explanation

Accelerated carbonate dissolution occurs because decreasing carbonic acid in groundwater reduces its solvent capacity, thus shifting the equilibrium to dissolve existing rock rather than precipitate more calcite onto stalactites; therefore dissolution occurs rather than stalactite growth.
