How is an ox-bow lake formed?

Meandering rivers form ox-Bow lakes. Rivers follow the path of least resistance when they erode their way through terrain, this is why rivers don’t always go in a straight path. This can make a river travel in sort of a “S” shape, but the water will always try and erode the soils in the direction of least resistance, eventually depositing soils and eroding away in different areas until a new path is formed making the longer more difficult old path obsolete. Eventually sediment gets deposited cutting off the old section of river all together. This abandoned section of river is called an Ox-bow lake.
