← GeographyWhich outcome results when river sediment deposition patterns shift?
A)Oxbow lake cutoff and formation✓
B)Increased riverbed downcutting rate
C)Widespread floodplain forest development
D)Regional water table level declines sharply
💡 Explanation
Oxbow lakes form due to increased sediment deposition, creating a meander cutoff via avulsion; this changes the river course, because the river favors a shorter, steeper path, therefore results in oxbow lake creation, rather than continued downcutting.
