This worksheet helps students understand topography by analyzing contour lines and elevation changes on Williams Hill and Jenkins Hill.

Let's solve the topography map activity step by step based on the provided image and information.

Understanding the Map

The map shows a topographic map with contour lines that represent elevation. Contour lines connect points of equal elevation. The spacing between the lines indicates the steepness of the slope:

- Closer lines = steeper slope
- Wider spacing = gentler slope

There is also a cross-section profile below the map showing elevation changes along a line from point A to B.

Elevations are marked in meters:
- 200 m, 300 m, 400 m, 500 m, 600 m, 700 m

We can determine the contour interval (the elevation difference between adjacent contour lines) by observing the labeled lines.

Step 1: Determine the Contour Interval

From the map:
- The labeled contour lines go from 200 m to 700 m.
- There are 5 intervals between these labels:
200 → 300 → 400 → 500 → 600 → 700
- So, each interval is 100 meters.

✔ Contour Interval = 100 meters

Answering the Questions

#### 1. Color the elevations on the topographic map as follows:
- 200m – Blue
- 400m – Red
- 600m – Purple
- 800m – Yellow
- 1000m – Green

⚠️ But wait — the highest elevation on the map is 700 m, so:
- 800m and 1000m are not present on this map.
- We only color:
- 200m → Blue
- 400m → Red
- 600m → Purple

👉 You would color the contour lines accordingly on the map (not possible here, but for the student).

#### 2. About how tall in meters is Williams Hill?

Look at the highest contour line around Williams Hill.

- The outermost contour near Williams Hill is 600 m.
- Inside that, there’s a 700 m contour line (since it's closed and higher).
- And inside that, there’s a 700 m label — but no higher labeled line.

Wait: The highest labeled contour around Williams Hill is 700 m, and since it's a hill, the peak must be higher than 700 m.

But we don’t have an 800 m line. However, the next contour after 700 m would be 800 m, but it's not shown.

But note: the innermost contour is 700 m, and since the hill is enclosed, the peak is above 700 m.

But we need to estimate.

Since the contour interval is 100 m, and the last contour is 700 m, the peak is between 700 m and 800 m.

So, Williams Hill is about 700–800 meters high.

But if we assume the peak is just above 700 m, we can say:

✔ About 700 to 800 meters (but likely closer to 750 m if it's halfway).

However, without more detail, the best answer is:

👉 Approximately 700 to 800 meters tall.

But since the question says "about," and the highest contour is 700 m, and the peak is inside, the elevation is greater than 700 m, but less than 800 m.

So, ~750 meters is a reasonable estimate.

✔ Answer: About 750 meters

#### 3. Which peak is taller and by how much?

We have two peaks:
- Williams Hill
- Another unnamed peak (likely the one on the left side)

Check their elevations.

- Williams Hill: Highest contour is 700 m, so peak > 700 m
- Other peak: Highest contour is 600 m, so peak > 600 m

But let's look at the labels.

On the map:
- Williams Hill has a 700 m contour line surrounding it.
- The other peak (left side) has a 600 m contour line.

So:
- Williams Hill peak: >700 m
- Other peak: >600 m

Assuming both peaks are just above their highest contours, and since the contour interval is 100 m:

- Williams Hill: ~750 m (estimate)
- Other peak: ~650 m (estimate)

Difference: ~100 meters

But let's be precise.

Actually, the other peak has a 600 m contour line, and it's inside a 500 m line, so it goes up to 600 m.

Wait — check the map again.

Looking at the map:
- The left peak is surrounded by a 600 m contour.
- So its peak is >600 m, <700 m → ~650 m
- Williams Hill is surrounded by a 700 m contour → peak >700 m → ~750 m

So:

- Williams Hill: ~750 m
- Left peak: ~650 m

Difference: 100 meters

✔ Williams Hill is taller by about 100 meters

#### 4. Starting at sea level, how many meters are in between each contour line on the topographic map?

We already determined this earlier.

The contour lines go: 200, 300, 400, 500, 600, 700 → every 100 meters.

So, the contour interval is 100 meters.

✔ Answer: 100 meters

---

#### 5. Which hill has a steeper slope?

To determine slope steepness, look at how close the contour lines are.

- Closer lines = steeper slope
- Farther apart = gentler slope

Compare:
- Williams Hill: The contour lines are close together near the peak.
- Other peak (left): The contour lines are more spread out.

So, Williams Hill has closer contour lines, meaning steeper slope.

✔ Answer: Williams Hill has a steeper slope

✔ Final Answers:

1. Color the elevations:
- 200m → Blue
- 400m → Red
- 600m → Purple
- (800m and 1000m not present)

2. How tall is Williams Hill?
→ About 750 meters (between 700 and 800 m)

3. Which peak is taller and by how much?
→ Williams Hill is taller by about 100 meters

4. Meters between each contour line?
→ 100 meters

5. Which hill has a steeper slope?
→ Williams Hill
