Which consequence results when focused wave energy erodes coastal headlands?

💡 Explanation

Intense wave energy concentrating on headlands promotes differential erosion; wave refraction shapes the coastline because weaker rock erodes faster forming stacks, therefore sea stacks form rather than sediment deposits which occur at low wave-energy zones.
