← GeographyWhich outcome decreases island size when wave diffraction occurs?
A)Amplified erosion behind island✓
B)Dissipation of energy offshore
C)Increased sediment deposition leeward
D)Uniform wave energy distribution
💡 Explanation
Amplified erosion occurs because wave diffraction focuses wave energy behind the island, concentrating erosive forces there, through wave refraction patterns. Therefore, erosion weakens the island from behind, rather than even distribution patterns.
