Which feature results when wave refraction focuses hydrodynamic energy?

💡 Explanation

Wave refraction concentrates energy on headlands; differential erosion scours weak points. This undermines the land, because positive feedback causes land scouring; therefore remnant headlands erode and creates sea stacks, rather than depositional features like deltas.
