It looks like you've uploaded a
Contour Map Worksheet #2 that includes a topographic map of part of North America and several questions related to interpreting contour lines, elevation, slope, and landforms.
Since I can't view or access images directly, I’ll need you to
describe the image or
type out the questions and the map details (e.g., contour intervals, labels, locations of points A–C, etc.) so I can help solve the problem step by step.
However, I can still guide you through how to solve typical contour map problems based on common formats. Here’s a general approach:
---
🔍 Understanding Contour Maps
-
Contour lines connect points of equal elevation.
-
Close contour lines = steep slope.
-
Wide-spaced contour lines = gentle slope.
-
Closed loops with higher values inside = hill or mountain.
-
Closed loops with lower values inside = depression (often marked with hachures).
-
V-shaped contours point upstream in valleys; the V opens toward higher ground.

🧩 Common Questions & How to Solve Them
#### 1.
What is the elevation at Point X?
- Look at the nearest labeled contour line.
- Use the
contour interval (usually given on the map, e.g., 100 ft or 50 m).
- Count up or down from the known line to find the elevation at the point.
> Example: If the contour interval is 100 ft, and Point A is halfway between 600 ft and 700 ft, then elevation ≈ 650 ft.
#### 2.
In what direction is the stream flowing?
- Streams flow
downhill, from higher to lower elevations.
- The
V-shaped contour lines point
upstream.
- So, the stream flows
opposite the direction the V points.
> Example: If the V points north, the stream flows south.
#### 3.
Which diagram best represents the profile from A to B?
- Draw an imaginary line from A to B.
- Observe the elevation changes along the way using contour lines.
- The profile should show
peaks and valleys matching the terrain.
- Steep slopes = steep parts of the profile; flat areas = gradual or flat terrain.
#### 4.
What is the approximate length of the river between points A and C?
- Use the scale bar on the map.
- Measure the distance between A and C with a ruler or string.
- Convert using the scale (e.g., 1 cm = 10 km).
#### 5.
What type of landform is shown at point C?
- Look at the contour pattern:
-
Circular closed contours = hill
-
Depression with hachures = sinkhole or basin
-
V-shape pointing uphill = valley
-
Contour lines crossing a river = stream valley

✔ Next Steps
Please provide:
1. The
contour interval (if not visible, assume standard like 100 ft or 50 m).
2. Elevation labels near Points A, B, C.
3. The exact wording of each question.
4. Any visible features (rivers, hills, depressions, etc.).
Once I have that, I can walk you through solving each question accurately.
