6. Practice
Close your hand into a fist with the fingers and thumb facing away from you.
Now pretend you are a tiny ant crawling across a fist.
From the ant’s point of view, what landform does the ridge of your knuckles look like?
How are your knuckles and a mountain range similar?

7. Practice
Lay the rectangle of plastic wrap horizontally across the knuckles of your fist.
Pull the overhanging section of plastic wrap on the outside of their hand underneath your palm and hold it in place with your thumb. Hold the other hanging piece to your palm.

8. Practice
Draw a line around each of your knuckles across the top of the fist.
Draw a second line around the outside of the first line on each knuckle.
Draw one line around all four knuckles.
Discuss and write your observations

10. Reading and Interpreting Topographic Maps
Application
Reading and Interpreting Topographic Maps

11. Topographic Map
A map that show the elevation of the land, such as hills and valleys, using contour lines.

12. Elevation
A term that describes the height of a point on Earth’s surface above (or below) sea level.
This point is 6300 feet (1920 meters) above sea level.

13. Features of a Topographic Map
Natural Features
Rivers, lakes
Mountains
Artificial (man made) features
Cities
Roads, bridges

14. Parts of a Topographic Map
Contour Lines
A line that connects points of equal elevation
Used to show features of the land
Mountains, valleys, etc

16. Spacing of contour lines depends on steepness of slope
Close = steep slope
Far apart = gentle slope

17. Types of Contour Lines
Or Gentle

18. Contour Interval
The difference in elevation between one contour line and the next
Spacing of lines depends on slope characteristics

19. Index Contour
A darker, bolder contour line that indicates a change in elevation
Usually found every fifth contour line

20. What is the contour interval in this example?20

21. What does contour line spacing indicate?
The closer together the contour lines are, the steeper the hill is. The more spread apart they are, the gentler the slope.
Traveling along the red line would be much steeper than traveling along the green line.

22. Which way is the stream flowing?
When contour lines cross a stream or river, they form v-shaped kinks in the lines that always point upstream.
Also remember - Water always flows DOWNHILL!
Blue Creek flow towards the East.

23. Finding the hill tops
Hill tops are easy to find. Just look for the concentric closed contour lines that form the top of a hill. Notice the contour lines that form the two peaks below.

24. What do those funny hachure marks mean?
Some features, such as the Grand Canyon, lakes, mines, or sinkholes actually are holes in the ground. The hachured contours indicate a depression. Don’t confuse it with a hilltop!
800
700
600

25. Relief
The difference between the highest elevation point and the lowest elevation point on a map
200
300
400
Units = meters
What is the relief of this map?
What is the contour interval of this map?
200 meters
100 meters

26. Satellite Map View
A map made of pictures of the Earth taken from a satellite orbiting the Earth
Andes Mountains Satellite Image:
Satellite orbiting planet:

27. Rules for Successful Contouring Golden Rule #1
Every point along a contour line represents the same elevation.
This entire line represents 1200 feet above sea level.
1200
1150
1250

28. Rules for Successful Contouring Golden Rule #2
Contour lines NEVER split or divide!
Can’t happen!
1150
1200
1150
1250

29. Rules for Successful Contouring Golden Rule #3
This is fine!
Contour lines cannot just stop. They must either form a closed loop, or run off the edge of your map.
What’s the elevation here???
1100
1200
1150
1250 ? ?

30. Rules for Successful Contouring Golden Rule #4
Contour lines NEVER, EVER cross
What’s going on?? Is this area above or below 1200 feet?
1100
1200
1150
1250 ?

31. Rules for Successful Contouring Golden Rule #5
Contour lines that cross a valley or stream are V-shaped
The V points towards the area of highest elevation

32. Rules for Successful Contouring Golden Rule #6
Tops of mountains or hills are shown by closed circles

TOPO QUIZ Now its time to test your topography map reading skills. Good Luck!!

34. What landform do you think this map depicts?
If you traveled from point A to point B, would you be going uphill or downhill?
What landform do you think this map depicts?
a. Valley
b. Mountain
c. Plain
700
750 A
800 X
825 B

35. Correct!

36. Sorry
Actually, you would be going uphill. Look at the elevations on the contour lines you will be crossing.

37. Sorry
Please try again.
