Reading a Landscape Off a Map
Contour lines carry the shape of the ground, and once you can read them a map tells you where a valley is steep, where a floodplain is, and where a spit is growing. Drawing a cross-section is how you check you have read it right.
What a learner can do afterwards
- Say what closely spaced contours mean, and what a V pointing upstream tells you
- Draw a cross-section between two grid references from contour values
- Find one river landform and one coastal landform on a map extract and name each

Contour lines join places that sit at the same height. They are the thin brown loops that cover the map. Where the lines crowd close together, the ground climbs fast and feels steep. Where they sit wide apart, the ground is flat or gentle.
Look for a V shape that points uphill. That V marks a valley, and a stream often runs out through its open end. Rings that close into circles mark a hill, and a number beside them tells you its height. You can tell the steeper valley by its narrow sharp V, where the lines pack tight.
Rivers leave bends and loops with flat land beside them. Coasts leave a wavy edge where land meets sea, sometimes with a narrow spit reaching out. To check your reading, pick two points, read the height at each, and sketch the rise and fall between them.
Plan a walk on the wide apart lines and keep off ground where lines merge into one. Merged lines mean a cliff, and cliffs are no place for a path.
Close lines mean steep ground, wide lines mean flat ground, and a V pointing uphill means a valley.
