Which feedback occurs when wave refraction focuses energy?

💡 Explanation

Formation accelerates because wave refraction causes positive feedback; concentrating wave energy to erode headlands transports and deposits sediment offshore through longshore drift, therefore barrier island expands offshore, rather than other options involving different geologic timescales or mechanisms.
