← GeographyWhich outcome occurs when deflation lowers the barrier island elevation?
A)Increased wave overwash vulnerability✓
B)Formation of offshore turbidites
C)Enhanced chemical weathering rates
D)Decreased longshore current velocity
💡 Explanation
Increased wave overwash results because lower elevation allows storm surges to penetrate further inland; this is coastal inundation as energy is no longer dissipating during wave breaking, therefore, the island becomes more vulnerable rather than turbidite formation or altered weathering.
