Q. What are oxbow lakes and how it is formed ?

Ans - Oxbow lake is a small lake located in an abandoned meander loop of a river channel. They are U-shaped or curved bends in a river that are cut off from the main river flow, forming a lake. Every river contains twists and turns or meanders, that cut through the surrounding landscape in a unique way. Due to continuous erosion and deposition along the sides of the meanders, the end of the meander loop comes closer and closer. In due course of time, the meander loops cut off from the river forming a lake called oxbow lake.

PLEASE MARK ME AS BRAINLIEST

Answer:

An oxbow lake starts out as a curve, or meander, in a river. A lake forms as the river finds a different, shorter, course. The meander becomes an oxbow lake along the side of the river. Oxbow lakes usually form in flat, low-lying plains close to where the river empties into another body of water
