Which risk increases when water tables decline in karst landscapes?

💡 Explanation

Increased sinkhole formation increases, as dropout sinkholes develop because the loss of water support destabilizes cave roofs and collapses overlying sediment; therefore, ground subsidence increases rather than less erosion affecting surface material.
