Which morphological outcome results when wave diffraction causes erosion unevenly alongside a headland?

💡 Explanation

Wave diffraction concentrates energy at headland sides causing differential erosion; this mechanical weathering forms arches, and pillar-like isolated sea stacks appear because arches collapse over time, rather than tombolo formation from sediment deposition.
