Can be used during a module on rivers. Students should make annotated diagrams to show the stage in the formation of an oxbow lake. They should then explain how the oxbow lake may disappear ...
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. On these plains, rivers often have wide meanders.
Today’s Wonder of the Day was inspired by Margie from Plainfield, IL. Margie Wonders, “How does an oxbow lake form?” Thanks for WONDERing with us, Margie! If you live near a river, you may have a certain type of lake in your area. If you look at a map and see a crescent-shaped lake not far ...
