Which mechanism accelerates sea stack erosion in temperate zones?

A)Freeze-thaw weathering
B)Halocline formation
C)Isostatic rebound
D)Scree accumulation

💡 Explanation

Freeze-thaw weathering accelerates sea stack erosion because water expands upon freezing in rock fissures, creating pressure which then fractures the rock; therefore, freeze-thaw spalling degrades stacks rather than other forms of chemical or mechanical weathering.
