← GeographyWhich outcome occurs when a large island shields a smaller island from prevailing winds across open ocean?
A)Increased wave energy on leeward coasts
B)Reduced erosion via wave refraction✓
C)Amplification of tidal bore formation
D)Enhanced sediment transport to outer reefs
💡 Explanation
A larger island causes wave energy dissipation because wave refraction bends waves around the larger island, reducing impact on the smaller island's leeward side; therefore less erosion occurs, rather than increased erosion or tidal effects.
