← GeographyWhich outcome threatens a small barrier islands when sea levels rise?
A)Increased wave refraction concentrates erosion✓
B)Subduction fault locking increases uplift
C)Decreased albedo causes global warming
D)Isostatic rebound accelerates beach progradation
💡 Explanation
Increased wave refraction around the island concentrates wave energy on smaller areas, accelerating the erosion process because wave energy dissipation decreases and convergence of wave crests intensifies the scouring action, therefore, the island erodes faster, rather than being uplifted, prograded, or indirectly warmed due to albedo influence.
