Which consequence results when excessive groundwater extraction destabilizes karst topography?

💡 Explanation

Increased sinkhole incidence results because groundwater extraction lowers the water table, thereby reducing pore pressure and decreasing the support for the overlying soils. This reduction triggers 'suffosion,' rather than slower speleothem changes, because the soil collapses.
