Contour lines and reliefFree1:18Heddy Score 3 of 7, below the standard
What you need to know
- Contour lines join places at the same height.
- Lines packed close together mean a steep slope, and lines spread far apart mean a gentler slope.
- Rings that get smaller and smaller mark a peak.
- Every fifth line is a thicker index contour with the height written on it, and the height change from one line to the next stays the same.
