← GeographyWhich outcome results when strong currents erode sediment supporting coastal stacks composed of limestone?
A)Increased wave refraction at stack base✓
B)Accelerated chemical limestone lithification
C)Stabilized coastal sediment aggregate formation
D)Enhanced sediment migration offshore
💡 Explanation
Wave refraction concentrates wave energy, especially as stack's integrity reduces with erosion; because wave intensity focuses towards the fragile based; therefore, refraction increases causing amplified erosion rather than other stabilization because of specific base damage patterns.
