← GeographyWhich process substantially alters the dimensions of an oxbow lake’s morphology after its formation?
A)Thermal stratification variation
B)Differential bank erosion rates✓
C)Ephemeral stream discharge influx
D)Regional isostatic rebound effect
💡 Explanation
After formation from river meandering cut-off, differential bank erosion occurs because varying sediment consistency along oxbow's perimeter causes unequal sediment removal by weak currents. Therefore dimensions change irregularly rather than uniform change imposed by other environmental effects, due to this spatially variable bank erosion.
