Which consequence results when undercutting of coastal sea stacks increases?

💡 Explanation

Accelerated stack collapse rate occurs because preferential erosion causes basal weakening of the stack. The mechanism is basal sapping. It undermines the structural integrity; therefore, stack failure increases rather than a stable base because continual wave action removes weathered material.
