Cross sections
Cross sections are line graphs that show a sideways view of a landscape. They can show features such as hills and valleys, or depths, such as the depth of a river.
Cross sections of hills use contour lineLine on a map joining points of equal height above sea level - thus representing the slope of the land. to determine the height of the land. Cross sections of river depths are drawn using negative numbers so that the line graph looks like depth, rather than height.
When interpreting cross sections, you should include:
- the highest and lowest points
- a comparison of different areas e.g. river bank compared to river bed or hillside compared to valley
- any anomalies i.e. things that you would not expect to see
