← GeographyWhich erosional outcome dominates after pyroclastic flow deposits?
A)Flash flood generation and subsequent incision✓
B)Long-term slope stabilization increases slowly
C)Localized CO2 pockets diminish plant transpiration
D)Glacial scouring accelerates in elevated terrain
💡 Explanation
Flash floods dominate erosion because unconsolidated pyroclastic material increases surface runoff via decreased infiltration. This concentrates intense flows on adjacent drainage basins, triggering rapid gully formation rather than steady accumulation because slope gradients are already high.
