Which risk markedly increases above limestone caverns when seasonal water tables surpass a critical saturation point?

💡 Explanation

Sinkhole formation is promoted by increased groundwater saturation because hydraulic pressure overcomes the mechanical strength of the already weakened carbonate rock via the dissolution process of carbonation. Therefore, sinkholes form preferentially during high groundwater events rather than geothermal activity.
