Which outcome occurs following substantial coastline erosion near sea stacks?

💡 Explanation

Increased wave energy impacts the mainland because the stacks, having diminished protection due to erosion, undergo increased wave refraction. This phenomenon concentrates wave energy on smaller areas rather than distributing it, therefore wave energy increases rather than decreases.
