← GeographyWhich process promotes barrier island merging during sea-level rise?
A)Overwash sediment redistribution maintains elevation✓
B)Tidal prism growth resists breaching
C)Sediment starvation reduces shoreline progradation
D)Dune stabilization reinforces island integrity
💡 Explanation
Overwash processes redistribute sediment during storms; this causes a redistribution of sediments over the island surface, raising the average elevation, because overwash transports sand landward from the beach and dunes enhancing resilience during sea-level rise, therefore islands merge, rather than erode in place.
