Which outcome results when excessive groundwater extraction accelerates limestone dissolution?

💡 Explanation

Increased extraction thins the saturated zone and enhances dissolution due to hydrostatic imbalances, leading to more frequent sinkhole formation because water now has less resistance when dissolving unstable surface minerals. Therefore, frequency increases rather than other options, which require saturated hydrostatic equilibrium.
