This is a topographic map with contour lines that show points that are on the same level. Here, the two hills are seen from the side, with elevations marked and dotted lines pointing to the corresponding contour lines. 1. Color the elevations on the topographic map as follows: 50m=Blue, 40m=Red, 30m=Purple, 20m=Yellow, 10m=Green. 2.
