← GeographyWhich outcome occurs when rising sea temperatures accelerate glacial melt and coastal erosion, disrupting sediment transport?
A)Increased coastal erosion downdrift areas✓
B)Stabilization of existing barrier islands
C)Uniform accretion along all coastlines
D)Reduced storm surge vulnerability overall
💡 Explanation
Increased sediment mobilization by glacial melt, with longshore drift redistributing sediment. It starves downdrift areas, increasing erosion there because sediment replenishment is interrupted; therefore, erosion intensifies rather than stabilizing coastal lands nearby from new soil deposition.
