Which outcome results when a meander erodes through its neck during enhanced streamflow?

💡 Explanation

An oxbow lake forms due to stream meander cutoff, where increased erosion during flooding leads to a channel breaching across the meander neck via avulsion; therefore, a separate water body forms, rather than an increase in sinuosity requiring more gradual processes.
