← GeographyWhich risk increases when vegetation diminishes along stream banks?
A)Increased stream bank erosion✓
B)Decreased groundwater infiltration rates
C)Reduced longitudinal sediment transport
D)Augmented hyporheic zone biodiversity
💡 Explanation
Increased erosion occurs because root systems provide bank stabilization utilizing mechanical interlocking; vegetation loss eliminates this protection. Therefore, erosion increases. Rather than decreased infiltration, the unvegetated soil often compacts, encouraging surface runoff.
