← GeographyWhich outcome results when coastal subsidence follows glacial retreat near islands?
A)Formation of extensive barrier islands
B)Increased rates of island erosion✓
C)Stabilization of existing coastal dunes
D)Decreased frequency of storm surges
💡 Explanation
Increased erosion occurs because the isostatic rebound lags behind subsidence, increasing relative sea level and wave attack following the Isostatic Adjustment mechanism. Therefore, B is correct; rather than barrier island formation, existing coastlines are subjected to greater inundation.
