  1. Unit 2:River LandscapesHow do Ox-bow lakes form?

  2. Let's focus on Ox-Bow Lakes! How are these formed?

  3. What is an Ox-Bow Lake? A horseshoe or semi-circular area that represents the former course of a meander. Ox-bow lakes are cut off from a supply of water and so will eventually become dry.

  5. Describe the formation of an Ox-bow Lake (4) • Use key language • Create a logical sequence by using connective phrases (‘over time’, ‘eventually’ etc.) • Describing change over time • Use an annotated diagram if you wish ‘Rivers can erode laterally. Erosion is greatest on the outside of the meander bend and forces the neck of the meander to narrow. At the same time, on the inside bend, deposition occurs. Over time, this will make the meander loop wider and the neck narrower. Eventually, the neck of the meander bends will join together and the meander is removed from the river current creating a crescent shaped feature called an Ox-bow lake’
