Which consequence results when groundwater table fluctuates substantially in karst landscapes?

💡 Explanation

Fluctuating water levels cause accelerated sinkhole formation because dissolution rates accelerate via effective stress changes due to increased pore pressure cycling which destabilizes subsurface cavities; therefore more sinkholes appear, rather than altered geothermal activity.
