What is the decisive stage in the formation of an oxbow lake?
Answer and explanation
Correct answer: Cutting of the meander neck and isolation of the old bend
An oxbow lake forms when lateral erosion narrows the meander neck and a flood allows the river to cut through the shorter route. The former loop is then abandoned and becomes separated from the main channel; deposition may later seal its ends. This neck cut-off and isolation is the decisive stage. Delta growth, wind-built sand forms, and glacial moraine deposition are unrelated processes.
