Which outcome accelerates the collapse of coastal sea stacks along rocky shorelines?

💡 Explanation

Salt crystallization within rock fractures widens them—a process called salt weathering—because crystal growth exerts pressure causing fractures to expand over time, therefore the stack’s structural integrity degrades. This happens rather than rebound lifting them, or vegetation growth.
