Which consequence results from prolonged groundwater depletion lowering supporting hydrostatic pressure within karst landscapes?

💡 Explanation

Groundwater depletion reduces hydrostatic pressure, initiating soil particle collapse; the mechanism is effective stress increase. This enhances surface subsidence, forming sinkholes, because reduced water pressure lessens supporting structures, therefore increased sinkhole risk rather than fracture cementation or slower cave formation.
