Which outcome limits island widening due to sediment deposition?

💡 Explanation

Erosion rates limit sediment accumulation because wave action and currents cause sediment dispersal (longshore drift) rather than concentration. Therefore, island widening halts because erosion prevents net sediment gain, rather than other stabilizing or uplifting mechanisms.
