Which outcome will accelerate barrier island erosion when longshore drift weakens?

💡 Explanation

Increased wave energy refraction causes localized erosion because without the sediment replenishment from longshore drift, waves focus energy on specific areas rather than distributing it evenly. Therefore, wave refraction increases erosion, rather than deposition, nutrient changes, or salinity impacts.
