Understanding the Map

This is a topographic map showing elevation using contour lines. Key features:

- Contour lines connect points of equal elevation.
- Closely spaced lines = steep slope; widely spaced lines = gentle slope.
- Closed loops with higher values inside indicate hills or mountains.
- "X" marks the highest point on Rock Mountain.
- Elevation is in feet.
- The contour interval is the difference in elevation between adjacent contour lines.

Step 1: Determine the Contour Interval

We are given several labeled contour lines:
- 800 ft
- 900 ft
- 1000 ft
- 1100 ft
- 1200 ft
- 1300 ft
- 1400 ft
- 1500 ft

Between each labeled line, the elevation increases by 100 feet.

So, the contour interval is 100 feet.

✔ Answer to Question 2: 100 feet

Step 2: Find Elevations at Points A, B, C, and D

#### Point A
- Point A is located on the 800 ft contour line.
- So, its elevation is 800 feet.

✔ A: 800 ft

#### Point B
- Point B is located on the 800 ft contour line, just above Fish Creek.
- It’s on the same line as A.
- So, elevation is 800 feet.

✔ B: 800 ft

#### Point C
- Point C is located inside the 1500 ft contour line but outside the 1600 ft line.
- The 1500 ft contour is the outermost one around the mountain.
- Since it's on the 1500 ft contour line, its elevation is 1500 feet.

✔ C: 1500 ft

#### Point D
- Point D is located between the 1000 ft and 1100 ft contour lines.
- But wait — look carefully: the contour lines go from 900 → 1000 → 1100 → 1200 → 1300 → 1400 → 1500.
- Point D is just below the 1000 ft line, and appears to be on the 900 ft line? Let's check.

Wait — actually, looking closely:
- There is a 900 ft contour line near the bottom left (near Lake).
- Then a 1000 ft line further up.
- Point D is on the 1000 ft contour line?

No — let's trace:

From the bottom left:
- The first labeled line is 900 ft.
- Then next is 1000 ft, then 1100 ft, etc.
- Point D is on the 1000 ft contour line.

Yes! It lies directly on the 1000 ft contour line.

✔ D: 1000 ft

✔ Final Answers:

#### 1. Elevation of each point:
- A: 800 ft
- B: 800 ft
- C: 1500 ft
- D: 1000 ft

#### 2. Contour interval:
- 100 feet

🔍 Explanation Summary:

- Contour interval is found by subtracting two adjacent labeled elevations:
900 ft – 800 ft = 100 ft → so every line goes up by 100 ft.
- Elevations are read based on which contour line the point lies on.
- If a point is on a contour line, its elevation is that value.
- If it were between lines, we'd estimate, but here all points lie on lines.

✔ Final Answer:

1.
A: 800 ft
B: 800 ft
C: 1500 ft
D: 1000 ft

2. Contour interval: 100 feet
