- APothole
- BLevee
- COxbow lake
- DFlood plain
Explanation
As a river meanders, deposition can cut off the neck of a meander loop, isolating the old bend as a crescent-shaped water body called an oxbow lake. Potholes are carved by abrasion in the riverbed, levees are natural embankments along the channel, and the flood plain is the wider valley floor. Hence the cut-off meander forms an oxbow lake.
