← GeographyAlong a chain of volcanic islands, which outcome occurs when a submerged fracture zone obstructs normal wave propagation?
A)Accelerated headland erosion on specific islands✓
B)Uniform sediment deposition across all islands
C)Decreased longshore drift regardless of geography
D)Increased isostatic rebound throughout the region
💡 Explanation
Wave refraction focuses energy on headlands, accelerating erosion because of wave convergence; this is preferential erosion, rather than uniform deposition or altered drift, therefore only specific islands see the amplified effect, influenced far more than isostatic rebound.
