Which outcome results when differential weathering weakens coastal rock formations?

💡 Explanation

The 'abrasion and hydraulic action' mechanism causes sea stacks to degrade faster because weaker sections erode first, which undermines the stack's structure; therefore, the structures collapse more frequently, rather than causing glacial formation or deposition, which are unrelated.
