An oxbow lake is formed from what?
Answer and explanation
Correct answer: Cut-off river meander
An oxbow lake develops when a river meander is cut off from the main channel. Continued lateral erosion narrows the meander neck, and during a flood the river may adopt a straighter course across the neck. Sediment then seals the abandoned ends, leaving a crescent-shaped water body. Therefore, option A is correct. A glacier crevasse, sand dune, and sea cliff arise from different processes and are not sources of oxbow lakes.
