Which shoreline transformation results when hydraulic action weakens sea stacks?

💡 Explanation

The breakdown of sea stacks by hydraulic action causes wave-cut platform expansion, because wave energy now directly impacts the base; therefore, the platform widens to dissipate it, rather than canyons or reef growth which involve downcutting or biologic processes.
