Which phenomenon accelerates sea stack disintegration when wave height increases?

💡 Explanation

Increased wave height amplifies hydraulic action, forcing water into cracks, because this mechanical stress rapidly exceeds sandstone yield strength, fracturing the stack; therefore, physical disintegration is sped up, rather than slower chemical weathering, or tidal fluctuations alone.
