Students should use annotated diagrams to explain the process that turn a meander into an oxbow lake. They should demonstrate the roles that flooding and the narrowing neck of land between the loops play in this process. Describe how continued deposition and build up of vegetation go on to cause the oxbow lake to disappear.
