An illustrated explanation of rivers and meanders.

First broadcast:

Students should create annotated diagrams explaining how a meander is formed, considering its horizontal appearance and cross section. They should relate this to the speed of water and the energy it has to erode or transport material. Link this feature to the specific types of erosion and transportation that water can demonstrate. Compare maps of the same river from different time periods to show how meanders move downstream and change shape over time.
