Which consequence results when storm frequency exceeds barrier island migration rates?

💡 Explanation

Increased erosion leads to island breakup because overwash processes (sediment transport across the island) dominate rather than allowing **longshore drift** to buffer equilibrium, thereby leading to increased landward sediment transport; therefore, land erodes faster, rather than normal reef or stack formation.
