Which risk increases when concentrated agricultural runoff occurs above karst topography?

💡 Explanation

Sinkhole formation increases due to dissolution. The concentrated acidic runoff accelerates the chemical weathering (dissolution) of limestone because the rock has less resilience; therefore, cave systems become unstable and are more prone to sudden collapse rather than remaining intact.
