Which outcome accelerates barrier island submergence where vegetation is sparse?

A)Increased wind erosion rate
B)Elevated sediment deposition rates
C)Enhanced bioaccumulation of mercury
D)Decreased wave energy dissipation

💡 Explanation

Higher wind speeds and less vegetation on barrier islands results in increased Aeolian Transport, therefore, sediment is removed by wind rather than stabilized by roots to maintain island height, because wind erosion transports sand away more readily resulting in the island failing to keep height.
