Which process sharply increases stress concentration within coastal sea stacks?

💡 Explanation

Wave refraction results in increased energy focused on promontories and stacks; the wave energy converges, which accelerates erosion because of increased hydraulic action. Therefore, wave refraction exacerbates scouring; rather than tidal resonance or isostatic effects which occur at larger scales.
