Which outcome occurs when groundwater rich in dissolved carbon dioxide percolates through limestone formations in an area experiencing prolonged drought?

💡 Explanation

Stalactite growth slows during droughts because calcite deposition is reduced by decreased infiltration and evaporation limits bicarbonate availability. Therefore, growth stalls rather than aquifers recharging, because less water enters the system, and evaporites or oxidation need different chemistry.
