Station #4: Contour Mapping Rules

Directions: Read these rules and use them to fill in the blanks for the Conclusion Questions.

1. A contour line represents a single equal elevation: that is, all points on the same contour line have the same elevation.2. Where one closed contour line surrounds another, the inner contour line represents the higher elevation.3. The elevation represented by a contour line is always a simple multiple of the contour interval.4. A contour line that closes within the limits of the map indicates a hill, ridge or plateau.5. Commonly, every fifth contour line (index contour) is darker and its elevation is shown.6. On the same map, closely spaced contour lines indicate a relatively steep slope, widely spaced contour lines indicate a relatively gentle slope, and uniformly spaced contour lines indicate a uniform slope.7. Contour lines do not cross other contour lines. Exception: on a vertical cliff or a nearly vertical cliff, contour lines touch because they are on top of one another8. Every contour line eventually closes against itself. However, the map area may not be large enough to show this closure. Therefore, the contours will end at the edge of the map.9. Closed depressions are shown by hachured contour lines. The hachures point into the depression. (Hachures = short dashes)10. A hachured contour line, lying between two different contour lines, is the same elevation as the lower contour line.

11. Where two adjacent contours indicate opposite slopes (hachured contour next to plain contour), both are the SAME elevation.12. Where a contour line crosses a stream or valley, the contour bends to form a “V” that points upstream or up the valley. Therefore the river flows opposite the direction of the “v”13. A topographic map is aerial view of a location with contour lines that indicate areas of equal elevation above sea level (sea level = 0m)

10. A ___________________________ is a side view of a particular area.

11. The ______________________ can be determined by estimating the distance between contour lines

Station #5: Critical Thinking (you can do it!)

An island measures 10 kilometers from east to west and 8 kilometers from north to south. A single hill on the east side of the island has a maximum elevation of 57 Meters and is steepest to the north. In the box below, draw a simple contour map to represent this island, using a distance scale of 1 centimeter = 1 kilometer and a contour interval of 10 meters.
