← GeographyWhich outcome commonly results when river downcutting slows and lateral erosion continues within a meander bend?
A)Oxbow lake formation✓
B)Increased sediment deposition
C)Accelerated floodplain development
D)Higher channel avulsion frequency
💡 Explanation
Oxbow lake formation results from continued lateral erosion, wherein the river takes a shorter, steeper path across the floodplain via channel cutoff; this is termed meander cutoff, because it shortens the channel; therefore, an oxbow lake forms, rather than the meander persisting.
