Which outcome occurs when wave action undermines a coastal arch, forming offshore stacks?

💡 Explanation

Removal of key structural support by differential erosion causes increased wave energy acting on nearby land, because the dissipation by the arch is removed; therefore storm impacts increase, rather than different sedimentary actions.
