Which outcome results when wave energy focuses along headlands of an island?

💡 Explanation

Differential erosion forms sea stacks because wave refraction concentrates energy on exposed headlands; hydraulic action and abrasion accelerate erosion there, rather than in sheltered bays. This process carves stacks rather than stabilizing dunes or reducing transport.
