Which erosional outcome is accelerated alongside existing sea stacks when increased storm surge occurs?

💡 Explanation

Increased storm surges enhance hydraulic action undermining because they deliver more powerful waves that compress air in cracks causing widening and stack collapse; therefore, weakening occurs due to physical force, rather than chemical or isostatic changes.
