Which risk increases when excessive groundwater extraction causes substantial land subsidence?

💡 Explanation

Coastal flooding increases because decreased land elevation from compaction due to the effective stress mechanism reduces the coastline's natural buffer against storms; therefore flooding is the increased risk, rather than more geothermal energy productivity.
