1. Contour Maps AKA Topographic Maps

2. Contour Map: (topograpic map) shows elevation of various points on the Earth’s surface.

4. Maps show p hysical features of land, such as cliffs, valleys, hills, and depressions.

6. Contour Lines: lines that connect points of equal elevation above sea level.

9. Are BOLDED Lines—they show the numerical values of the lines. All other lines are unlabeled.

10. Contour Interval: Difference in elevation between two contour lines

12. What is the contour interval of this map?

13. Points on contour lines

14. Points between contour lines

15. Depression: hole or crater on the Earth’s surface, shown on a contour map by Hachured Lines

16. The first hachured line has the same elevation of the lowest contour lines between which it was found.

19. Highest possible points This location is between 220 and 240

20. Contour lines crossing a river

21. Time to Practice!

23. Profile: Shows the Hills and Valleys (ups and downs) on a line across any part of a contour map.

33. Notice how the line curves above the 40 mark, but below the 50

35. If the graph isn’t directly below the map…..
