Which consequence results when a barrier island erodes?

💡 Explanation

Increased mainland shoreline erosion occurs because barrier island loss exposes the coast to incoming wave energy, disrupting the process of wave attenuation. This leads to direct wave attack rather than energy dissipation by the barrier island; therefore, mainland erosion increases.
