Which outcome occurs when a coastal headland collapses supporting a sea stack during high tides?

💡 Explanation

Increased wave energy focuses on the newly exposed stack leading to further erosion via hydraulic action accelerating longshore sediment transport, because the protective barrier of the headland is gone, therefore sediment erodes faster rather than depositing due to reduced wave action behind the headland.
