← GeographyWhich outcome occurs along coastlines during repeated storm surges?
A)Barrier island migration increases swiftly✓
B)Marine terraces form with uplift
C)Estuarine salinity decreases overall
D)Littoral sand accretion accelerates sharply
💡 Explanation
An increase in barrier migration increases swiftly during surges, because wave action enhances sediment transport driving **longshore transport**. Severe surge erosion surpasses deposition, therefore the islands move landward at a faster rate than natural cycles, rather than forming terraces.
