Which outcome results when continued wave action erodes a sea stack's base?

💡 Explanation

Wave action erodes the base of structures via hydraulic action because water and air trapped in cracks compress under wave impact; a destabilized structure has elevated risk of collapse. Therefore, collapse risk increases, rather than altered sediment transport because sediment transport relates to grains moved by shallow longshore drift.
