Which outcome typically occurs on barrier islands due to variations in wave energy along the shore?

💡 Explanation

As wave energy varies, longshore drift causes sediment deposition leading to spit progradation strengthening barrier islands, because this preferential sediment sorting extends the island further along the coast. Therefore, a seaward extension, rather than uniform distribution or hindered dune development emerges.
