Which outcome commonly results when a river encounters differential erosion around a meander?

💡 Explanation

Oxbow lake formation occurs due to differential erosion widening the meander's neck. Channel avulsion then occurs; therefore, a cutoff meander forms an oxbow lake rather than continual deposition because erosion creates an unstable channel path.
