Using OS maps to analyse physical features
I can use contour lines to identify and describe physical features on a map.
Lesson details
Key learning points
- The height of the land can be shown on a map using spot heights and contour lines.
- The shape of the land can be shown on a map by examining how contour lines relate to each other.
- Distinctive patterns of contour lines show particular physical features on a map.
Keywords
Relief - the shape of the land
Contour lines - lines on a map that join points of the same height
Spot height - a point marked on a map showing a particular height
Common misconception
All contour lines have their height marked on them.
Most contour lines will show their height, but in very steep areas, where contours are close together, some will be omitted as there is a lack of space. The height of these lines can be calculated by looking at the height of the surrounding lines.
A large potato cut in half length ways will give students a 'hill' on which they can mark contours at 1cm intervals. The more misshaped the potato, the more variation there will be in the gradient and the contour line patterns produced.
