← GeographyWhich outcome occurs when vegetation loss destabilizes alluvial terraces?
A)Increased frequency of debris flows✓
B)Reduced rates of chemical weathering
C)Decreased hyporheic zone activity
D)Diminished floodplain sedimentation rate
💡 Explanation
Increased debris flows occur because vegetation anchors soil; removal leads to hillslope instability, promoting **slope failure**. Without root cohesion, gravity overcomes friction therefore soil mass mobilizes faster rather than remaining stable and allowing weathering.
