Use an OS map to:

  • describe the physical characteristics of a river and its valley
  • compare and contrast the physical features of two rivers and their valleys
  • annotate a base map to show the physical characteristics of a river and its valley.

With the aid of a diagram(s):

  • explain the formation of selected physical features of a river and its valley: e.g. waterfall, levee, river terrace, meander, braiding, flood plain, alluvial fan
