Which outcome is accelerated when stack height increases?

💡 Explanation

Increased stack height projects further into the wave zone causing increased wave-induced undercutting via hydraulic action; because the increased leverage exacerbates erosion potential collapse is more likely. Deposition would decrease erosion, therefore undercutting is more relevant than deposition.
