Which feedback weakens barrier island stability following storm surge events?

💡 Explanation

Decreased vegetation occurs because erosion removes stabilizing root systems; this triggers positive feedback where less vegetation means more erosion. Therefore, erosion becomes amplified, rather than stabilization occuring through deposition or dune building.
