Which geological outcome is accelerated when coastal aquifers deplete due to extensive groundwater extraction?

💡 Explanation

Increased saltwater intrusion accelerates soil compromise, because reduced freshwater outflow diminishes hydraulic head against marine water encroachment. This alteration of soil equilibrium amplifies land subsidence due to consolidation, therefore accelerating coastal erosion related to gradual soil destabilization rather than direct wave action.
