← GeographyWhich outcome accelerates isolated sea stack erosion when wave diffraction occurs?
A)Increased sediment deposition near base
B)Concentrated wave energy at sides✓
C)Reduced chemical weathering exposure
D)Expanded biological colonization surfaces
💡 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.
