Explanation:
Let’s go through each question step by step using the topographic map and profile view.
1.
Coloring elevations — This is an instruction, not a question to answer here. We’ll skip it since the rest are questions.
2.
Approximately how tall is Able Hill?
Look at the profile view (side view). The base of Able Hill is at sea level = 0 m. The top of Able Hill reaches just below the 40 m line — actually, the contour line labeled “40” wraps around the peak, meaning the peak is *at least* 40 m. But the next contour line inside would be 50 m (since contour interval is 10 m — see Q5), and there is no 50 m line inside Able Hill’s innermost loop — only the 40 m line is shown as the innermost closed contour. That means the peak is
between 40 m and 50 m, but not reaching 50 m. In the profile view, the peak aligns with ~45 m (midway between 40 and 50). So approximate height =
~45 meters.
Wait — double-check: In the plan view, Able Hill has a closed 40 m contour, and *no* 50 m contour inside it. That means the elevation is
greater than 40 m but less than 50 m. Since the profile shows the peak slightly above the 40 m line but well below 50 m, ~45 m is reasonable.
3.
Approximately how tall is Baker Hill?
In the plan view, Baker Hill has a closed 50 m contour inside it (the innermost loop is labeled “50”), and no 60 m contour inside. So its peak is >50 m and <60 m. In the profile view, Baker Hill’s peak reaches just above the 50 m line — looks like ~55 m. So approximate height =
~55 meters.
4.
Which mountain is taller, and by about how much?
Baker Hill (~55 m) > Able Hill (~45 m). Difference ≈ 55 − 45 =
10 meters.
5.
What is the contour interval?
Look at the labeled contour lines: 10, 20, 30, 40, 50 — each increases by 10. So contour interval =
10 meters.
6.
Which mountain has steeper slopes?
Steeper slopes = contour lines closer together (because same elevation change over shorter horizontal distance). Compare the spacing of contours on each hill:
- Able Hill: From 10 m to 20 m to 30 m to 40 m — the rings look fairly evenly spaced, but the horizontal width (in plan view) from base to peak is wider.
- Baker Hill: Contours also go 10–20–30–40–50, but in the profile view, Baker Hill rises more sharply — the slope is steeper (higher rise over shorter horizontal distance). Also, visually in the plan view, the contour lines around Baker Hill are packed more tightly near the peak than Able Hill’s.
So
Baker Hill has steeper slopes.
7.
Are the contour lines closer together on Able Hill or Baker Hill?
As just reasoned: On Baker Hill, the contour lines are closer together (especially near the summit), indicating steeper terrain. So answer:
Baker Hill.
Now verify all:
- Q2: Able Hill peak ≤50, >40 → ~45 m
✔
- Q3: Baker Hill peak ≤60, >50 → ~55 m
✔
- Q4: 55 − 45 = 10 m
✔
- Q5: 10 m interval
✔
- Q6 & Q7: Baker Hill steeper, lines closer there
✔
Final Answer:
2. About 45 meters
3. About 55 meters
4. Baker Hill is taller by about 10 meters
5. 10 meters
6. Baker Hill
7. Baker Hill
