Which outcome is accelerated as barrier islands destabilize?

💡 Explanation

Increased saltwater intrusion results from barrier island breakdown, because wave action exposes the land behind the islands, enabling greater marine inundation. This overwash process accelerates saltwater penetration, therefore saltwater intrusion increases, rather than the geological processes listed in the other options.

• Which landform immediately results from subsurface carbonate dissolution?
• Which phenomenon limits phytoplankton growth during deep coastal upwelling events?
• Which crustal outcome is caused by isostatic rebound following subduction?
• Which outcome results when soil shear strength decreases during solifluction?
• Which cascading failure results when thermokarst degradation compromises Arctic infrastructure?
• Which biogeochemical effect occurs when coastal upwelling is suppressed due to stronger subtropical gyre stratification?
