Oxbow lakes are generally formed by 1. erosion, resulting in a sudden increase in the streams gradient 2. deposition, resulting in a sudden increase in the streams gradient 3. erosion along the outside banks of the curve in a meandering stream 4. deposition along the outside banks of the curve in a meandering stream

Oxbow lakes are generally formed by erosion along the outside banks of the curve in a meandering stream

Option C

Explanation:

Erosion along the outside banks of the bend in a winding stream. An Oxbow Lake is framed when the dissolving activity of a waterway shapes a wander. The disintegration by the water makes the wind bended over some stretch of time.

With disintegration, the neck of the wander moves toward, becomes smaller and in the end of the waterway slices through the neck during a flood or when the water comes at an extremely rapid. This cutting of the wander structures what is known as an oxbow lake.
