← GeographyWhich feedback weakens barrier island stability following storm surge events?
A)Erosion reduces vegetation cover✓
B)Accretion increases sediment deposition
C)Submergence alters salinity profiles
D)Overwash enhances dune formation
💡 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.
