Topographic map lab activity worksheet with questions on elevation, contour lines, and profile creation.

The image you provided is a topographic map activity worksheet. Below, I will outline the solution to each question based on the typical features of a topographic map and the information typically included in such maps.

Part 1: Map Analysis

#### 1. What is the scale of this map?
- The scale is given at the bottom of the map as "1 cm = 200 m." This means that 1 centimeter on the map represents 200 meters in real life.

#### 2. What is the contour interval?
- The contour interval is the vertical distance (elevation difference) between two adjacent contour lines. From the legend or the map, it is stated as 50 meters.

#### 3. What do the circles on the left side of the map indicate?
- The circles on the left side of the map represent benchmarks or points with known elevations. These are used as reference points for measuring elevation.

#### 4. Why do contour lines do as they cross over a stream?
- Contour lines bend upstream when they cross a stream. This is because streams flow downhill, cutting through the land. The contour lines follow the shape of the valley created by the stream, bending upward toward the source of the stream.

#### 5. In which direction is the stream flowing?
- Streams flow downhill. To determine the direction, look at the contour lines near the stream. The stream flows from higher elevation to lower elevation. Based on the orientation of the map (assuming north is up), the stream appears to flow generally southward.

#### 6. What is the elevation of the campus and lake? Is it flat or steep?
- Campus Elevation: The campus is located in an area where the contour lines are widely spaced. This indicates that the campus is relatively flat.
- Lake Elevation: The lake is surrounded by contour lines that are closely spaced near its edges, indicating steeper slopes around the lake. However, the lake itself is at a constant elevation (the water surface is level).

#### 7. What is the elevation at the top of the hill?
- Locate the highest point on the map, which is labeled as "Hilltop." The elevation can be determined by looking at the contour lines surrounding it. If the highest contour line near the hilltop is labeled as 400 meters, and the next contour line above it would be 450 meters (based on the 50-meter contour interval), then the elevation at the top of the hill is likely between 400 and 450 meters.

#### 8. If you decided to walk from point P to point Q, what sort of topography would you encounter?
- Point P is located near the bottom left of the map, and point Q is located near the top right. Walking from P to Q involves:
- Starting at a low elevation near the stream.
- Climbing uphill as you move toward the center of the map, crossing several contour lines.
- Reaching a high elevation near the hilltop.
- Descending slightly as you approach point Q, which is near the lake.

#### 9. How many hills are located on this map?
- A hill is identified by a closed contour line with higher elevations inside. From the map, there is one prominent hill labeled as "Hilltop."

#### 10. On the grid below, draw a profile of the landscape along the line AB. Make sure to include the hillup in your profile.
- To draw the profile:
1. Identify the line AB on the map.
2. Note the elevation at various points along AB by observing the contour lines intersected by AB.
3. Plot these elevations on the vertical axis of the grid, with distance along AB on the horizontal axis.
4. Connect the points to create a smooth profile that shows the rise and fall of the terrain, including the hill.

Final Answer Summary

1. Scale: 1 cm = 200 m
2. Contour Interval: 50 meters
3. Circles: Benchmarks
4. Contour Lines Over Stream: Bend upstream
5. Stream Direction: Southward
6. Campus/Lake Elevation: Campus is flat; Lake is level but surrounded by steep slopes
7. Hilltop Elevation: Between 400 and 450 meters
8. Topography from P to Q: Low elevation near stream → uphill climb → high elevation near hilltop → slight descent near lake
9. Number of Hills: 1
10. Profile: Draw a profile showing the rise and fall of terrain along AB, including the hill.
