← GeographyWhich outcome results when wave diffraction is amplified around coastal sea stacks?
A)Localized sediment deposition behind stacks✓
B)Accelerated stack weathering via saltation
C)Reduced longshore current water volume
D)Increased beach face slope steepening
💡 Explanation
Amplified wave diffraction causes decreased energy immediately behind the sea stacks; this leads to reduced sediment transport in the lee, because sediment falls out of suspension leading to localized sediment deposition rather than continued erosion.
