← GeographyWhich outcome accelerates cliff retreat weathering when wave approach weakens the fault?
A)Increased wave energy transmission inland
B)Reduced sediment supply blockage
C)Elevated pore water pressure✓
D)Enhanced biological reef consolidation
💡 Explanation
Accelerated cliff retreat occurs due to elevated pore water pressure, because weak rocks get saturated and destabilized by tidal mechanics and the Wave Pumping weakens the materials. Therefore, saturation increases weathering, rather than preventing it.
