Which outcome occurs when sandstone sea caves experience increased wave action during storm surges?

💡 Explanation

Arch collapse and stack formation results from hydraulic action: water pressure widens fractures. Because this physical erosion surpasses chemical weathering, cave integrity weakens during storm surges; therefore arches fail, rather than sediment accumulating through depositional processes.
