← GeographyWhich outcome commonly results when alluvial riverine plains experience incision?
A)Terrace formation along valley sides✓
B)Enhanced floodplain sediment deposition
C)Increased channel sinuosity development
D)Widespread wetland ecosystem expansion
💡 Explanation
Terrace formation occurs due to river incision, where the river cuts down into its former floodplain because energy increases. Therefore, distinct, elevated surfaces form on valley sides rather than increasing alluvial deposition because incision reduces overbank flow.
