What is an isolated water body made from a cut-off old meander called?
Answer and explanation
Correct answer: Oxbow lake
The governing concept is meander cutoff. A river bend becomes increasingly curved as erosion attacks the outer banks and deposition builds the inner banks. During a flood, the river may cut through the narrow neck and adopt a straighter course; the abandoned horseshoe-shaped loop then remains as an isolated oxbow lake. Therefore, option B is correct. A lagoon is coastal, a kettle lake is glacial, and a cave is underground.
