Which risk increases where coastal cliff erosion forms sea stacks?

💡 Explanation

Increased wave energy focusing locally enhances erosion pathways; the stacks concentrate wave action. Wave Refraction occurs because the stacks interrupt normal wave propagation, therefore localized erosion increases, rather than decreased deposition downstream without sediment sources.
