Which risk increases when groundwater flows through fractured limestone formations?

💡 Explanation

Increased groundwater flow leads to greater chemical weathering, and thus karst topography evolution through dissolution; this enlarges fractures due to carbonic acid, which weakens the rock, because dissolution removes the mineral cement. Therefore, sinkhole formation is accelerated, rather than mitigated, due to the loss of structural integrity.
