Which risk drastically increases when groundwater acidity increases flowing through karst?

💡 Explanation

Increased groundwater acidity enhances chemical weathering, leading to increased limestone dissolution by dissolution; therefore, sinkhole formation risk increases, destabilizing construction, rather than other hydrological cycle alternations, because it directly weakens the bedrock's structural integrity.
