Which outcome contributes to sea stack formation when waves erode coastal cliffs?

💡 Explanation

Hydraulic action causes rapid joint fracture because pressurized water enters rock crevices, weakening them faster than weathering processes; therefore, stacks form detached, rather than landscape uplift causing gradual elevation, or purely chemical/thermal weakening.
