Which risk increases when groundwater saturation affects fissured bedrock?

💡 Explanation

Karst subsidence risk increases with water saturation because dissolution widens fissures, decreasing bedrock strength. Mechanical weathering through hydraulic action ensues, weakening structures; therefore, surface subsidence accelerates, rather than ore deposition, bioweathering reduction, nor increased CO2 sequestration.
