, UNIT 1: CONTOUR LINES
 These are lines drawn on maps to show the height of land above se
level
 Looking at the photo alongside we see the hill at the top and then
we see how it looks on a map with its contour lines underneath
 Contour lines join all the places that are the same height above sea
level, which is 0 m
This is written simply in metres
Contour lines are either higher or lower than the one next to it
The height difference between two contour lines is called the contour
interval
This difference is 20 m between each contour
These are brown in colour
