Which outcome occurs when rapid groundwater extraction amplifies existing fracture networks above confined limestone aquifer systems?

💡 Explanation

Surfacewater sinks occur because increased effective stress due to groundwater decline accelerates the **mechanical weathering** of bedrock. The surface collapses into voids rather than causing widespread downcutting; therefore, sinkholes form through spalling.
