Which outcome accelerates in a weathering sea stack subject to intense hydraulic action?

💡 Explanation

Increased undercutting occurs because hydraulic action, the mechanism, forces air and water into cracks, weakening the base; therefore the stack collapses sooner, rather than forming ridges caused by differential erosion rates higher up.
