Which consequence results when wave refraction weakens coastal sea stacks?

💡 Explanation

Wave refraction concentrates energy on headlands but disperses it in bays; therefore stacks erode non-uniformly, leading to collapse that feeds sediment into the longshore transport system, because the sediment source increases, rather than offshore island formation, crystal growth, or upwelling.
