← GeographyWhich consequence results when a migrating barrier island submerges?
A)Increased mainland erosion risk✓
B)Accelerated deep ocean upwelling
C)Reduced coastal salt marsh area
D)Decreased offshore sediment deposition
💡 Explanation
Increased mainland erosion occurs because submergence removes the island's 'wave shadow,' increasing wave energy on the coast, therefore mainland is exposed to greater hydraulic action, rather than offshore effects which cause other issues under appropriate conditions.
