Which process increases collapse risk above karst regions?

💡 Explanation

Lowering the water table diminishes hydrostatic support, expanding existing cave systems by solutional widening and causing increased land subsidence because reduced buoyancy increases stress. This mechanical unloading therefore raises sinkhole collapse hazard rather than volcanic deposition's limited impact.
