Which outcome accelerates isolated sea stack erosion when wave diffraction occurs?

💡 Explanation

Focused wave energy at the sides of the stack causes faster erosion because wave diffraction concentrates wave power therefore, the stack erodes more quickly from the sides, rather than experiencing uniform weathering all around.
