← GeographyWhich landform evolution occurs because wave refraction focuses energy?
A)Barrier island breaching and overwash✓
B)Increased river delta sediment deposition
C)Uplift of coastal terraces along faults
D)Intensified volcanic activity increase runoff
💡 Explanation
Barrier island breaching arises from wave refraction concentrating energy, initiating erosion; the mechanism is differential sediment transport because focused hydraulic action exceeds the barrier's resilience, therefore, overwash occurs rather than uniform shoreline retreat.
