Solved Topographic Map Worksheet Base your answers to the | Chegg.com - Free Printable

Since you mentioned you uploaded an image with a task, but no image is visible in this interface (as this is a text-based chat), I’ll provide a general explanation of how to solve each of these topographic map questions based on standard map-reading principles. If you can describe the map or upload it again via a platform that supports images (like Google Drive, Imgur, etc.), I can give exact answers.

For now, here’s how to approach each question:

---

3a. Calculate the Gradient between C and D

Gradient = (Change in Elevation) / (Horizontal Distance)

1. Find elevation at point C and point D from contour lines.
2. Subtract: Elevation_D – Elevation_C = ΔElevation (in feet).
3. Measure horizontal distance between C and D using the map scale (e.g., 1 inch = 1 mile).
4. Convert distance to same units as elevation (usually feet).
5. Divide: Gradient = ΔElevation (ft) / Distance (ft)

> *Example:* If C is 900 ft, D is 1500 ft → ΔE = 600 ft. Distance = 1 mile = 5280 ft → Gradient = 600/5280 ≈ 0.1136 (or 11.36%)

3b. Calculate the Gradient between A and B

Same method as above.

Find elevations at A and B, find difference, divide by horizontal distance.

4. In what direction does Fish Creek Flow?

Creeks flow downhill, perpendicular to contour lines, from higher to lower elevation.

- Look at contour lines near Fish Creek — they will “V” upstream.
- The point of the “V” points upstream (toward higher elevation).
- So, the creek flows opposite the direction the “V” points.

> *Example:* If the V points north → creek flows south.

5. What is the elevation of Point X?

- Locate Point X on the map.
- See which contour lines it lies between.
- If it’s on a contour line, read its value.
- If it’s between two contours, interpolate (e.g., halfway between 1100 and 1300 → 1200 ft).

6. Which cross section best represents the profile along straight line AB?

- Trace line AB across the map.
- Note elevation changes: where it goes up, down, peaks, valleys.
- Match that shape to one of the 4 graphs.

Look for:
- Starting and ending elevations at A and B.
- Highest point(s) along the line.
- Steepness/slope changes.

> *Hint:* Contour lines close together = steep slope; far apart = gentle slope.

Compare to profiles:
- (1) Gradual rise, peak, then fall — common for ridge.
- (2) Symmetrical peak — likely a mountain summit.
- (3) Deep valley — unlikely if AB crosses high ground.
- (4) Asymmetrical — steeper on one side.

Choose the one matching your traced profile.

7. Which side of Rock Mountain is the steepest? (compass direction)

- Look at contour lines around Rock Mountain.
- Where contour lines are closest together → steepest slope.
- Determine compass direction (N, NE, E, SE, S, SW, W, NW) of that side.

> *Example:* If contours are tightest on the southeast side → answer = Southeast

8. Which side of Rock Mountain has the gentlest slope? (compass direction)

- Opposite of #7: where contour lines are farthest apart.
- That’s the gentlest slope.
- State compass direction.

> *Example:* If contours are widely spaced on the northwest side → answer = Northwest

✔ To get precise answers, please describe:
- Elevations at points A, B, C, D, X
- Contour interval (e.g., 200 ft, 100 ft)
- Direction of “V” shapes in Fish Creek
- Shape of contour lines around Rock Mountain
- Map scale (e.g., 1 inch = 1 mile)

Or upload the image again via a supported platform.
