A rapid drop in the local water table triggers which sinkhole mechanism?

💡 Explanation

Rapid water table decline leads to reduction of pore pressure, therefore the mechanism causing sinkholes is support removal of sediment infill, because there is less buoyant support; rather than weathering or hydrostatic pressure increases.
