Across a volcanic barrier island, which consequence arises from diminished longshore drift processes?

💡 Explanation

Increased wave energy shoreward occurs because reduced sediment transport via longshore drift decreases natural coastal defenses against incoming waves; therefore more wave energy interacts with the shoreline, rather than being dissipated by sediment buffer.
