Which triggers rapid sinkhole formation above limestone bedrock?

💡 Explanation

Sinkholes form via differential erosion, the mass wasting from dissolution. Decreased groundwater raises the water table, triggering roof collapse because less buoyant support, therefore a sudden sinkhole forms upstream, as opposed to gradual soil weakening/stabilizing elsewhere.
