Which consequence results when excessive groundwater extraction dewaters an aquifer near karst topography?

💡 Explanation

Excessive groundwater extraction reduces pore water pressure, leading to decreased support for overlying sediments causing accelerated *mechanical weathering*. Therefore, sinkhole formation accelerates because this subsidence occurs rather than other effects related to surface water dynamics.

• Which outcome results when excess sediment deposition narrows stream channels on floodplains?
• Which effect primarily drives the deflection of large-scale atmospheric circulation patterns?
• Which action promotes dune stabilization in arid regions?
• Which risk increases when coastal foredunes erode further?
• Which geographic outcome is accelerated by enhanced carbonic acid dissolution?
