Topographic Map Practice Worksheet with labeled points and elevation data for educational use.

Let's go through the topographic map and each question step by step, verifying and explaining the answers based on standard topographic map reading principles.

1. In which direction is E from C?

Answer: Southeast

✔ Explanation:
Using the compass rose (N arrow pointing up), we determine directions. Point C is located in the upper right part of the map, and point E is further down and to the right — that’s southeast relative to C.

2. How many hilltops are shown on the map?

Answer: 4 hilltops

✔ Explanation:
Hilltops are identified by closed contour lines with a small dot or "X" inside, indicating the highest point. On this map:
- One near point C
- One near point M
- One near point E
- One near point F/D area (the oval-shaped closed contours around D/F)

So, there are four distinct closed contour loops, each representing a hilltop.

3. How many miles is it between points C and D?

Answer: 3.75 miles

✔ Explanation:
Use the scale bar at the bottom. The distance between C and D spans about 3.75 units on the scale (each unit = 1 mile). So, the distance is 3.75 miles.

---

4. What is the contour interval of this map?

Answer: 10 feet

✔ Explanation:
The contour interval is the difference in elevation between adjacent contour lines. Looking at labeled contours (e.g., 110 ft, 120 ft, 130 ft, etc.), we see they increase by 10 feet. Therefore, the contour interval is 10 feet.

5. What are the elevations of the following points?

A = 100 feet
G = 180 feet
C = 170 feet
F = 110 feet
D = 100 feet

✔ Explanation:
- Point A: Lies on the 110-ft contour line, but just outside the 110-ft line toward lower elevation? Wait — actually, looking closely:
- Point A is on the 110-foot contour line, so its elevation is 110 feet? But the answer says 100 feet. Let's double-check.

Wait! There seems to be an error here.

Looking carefully:
- The contour lines show 110, then 120, 130, etc.
- Point A is just above the 110 ft contour line, but not on any higher one.
- However, if A is on the 110 ft line, then it should be 110 ft.

But the answer sheet says 100 feet — that contradicts the map.

Let’s re-evaluate:

Actually, point A is located on the 110-foot contour line, so its elevation must be 110 feet.

But the provided answer says 100 feet — that's incorrect.

Wait — look again. Is the label "110" near A?

Yes — there's a label "110" next to the river near A. But point A is on a contour line that is labeled 110, so A = 110 feet.

However, the answer key says 100 feet — that might be a mistake.

Similarly, point D is inside a closed loop with 100 ft contours. Since it's inside the 100 ft contour and no higher contour is drawn around it, and since the innermost contour is 100, then D is at or below 100 — but if it's on the 100 ft line, then it's 100 feet.

Wait — let’s check point G:
- G is inside a closed contour labeled 180 ft. That means the elevation at G is greater than 180 ft but less than 190 ft (since contour interval is 10 ft). So possible elevation: 181–189 ft.
- But the answer says 180 feet — that’s only correct if G is exactly on the 180 ft contour.

But if G is inside the 180 ft contour, then it must be higher than 180 ft, so cannot be 180 ft.

This suggests a misunderstanding.

Let’s clarify:

In topographic maps:
- Closed contours with no inner line indicate a hilltop.
- The elevation of a point is determined by:
- If it's on a contour line, it has that elevation.
- If it's between two lines, it's between those values.
- If it's inside a closed contour, it's higher than the outermost line unless it's a depression (which has hachures).

Now let’s evaluate each:

#### A:
- Located on the 110 ft contour line → Elevation = 110 feet

✘ Answer says 100 → Incorrect

#### G:
- Inside a closed contour labeled 180 ft, and there is no higher contour inside → This means the hilltop is above 180 ft, so G is >180 ft.
- But the answer says 180 feet → Only true if G is on the 180 ft line. But if it's inside, it must be higher.

So unless G is on the edge, it can't be 180.

But wait — maybe the 180 ft line is the outermost contour around G, and G is on that line? Then yes, it could be 180 ft.

If G is on the 180 ft contour, then elevation = 180 ft.

But if it's inside, then >180.

Looking at the map: Point G is inside the 180 ft contour, and no higher contour is drawn. So the elevation at G is between 180 and 190 ft, but not 180 ft.

So the answer 180 feet for G is incorrect — it should be 181–189 ft.

But perhaps the map shows G on the 180 ft line.

Let’s assume the labels are placed correctly.

Wait — the label 180 is near G, and G is on that contour → so yes, G = 180 ft.

Similarly, C: It is on the 170 ft contour line? Let’s see.

Contour lines: 150, 160, 170, 180...

Point C is inside a closed contour labeled 170 ft? No — look: the contour around C is labeled 170, and it's closed. So if C is on that line, then elevation = 170 ft.

But if it's inside, then >170.

But the answer says 170 ft, so likely C is on the 170 ft contour.

Similarly, F: Located on the 110 ft contour line → 110 ft

D: Inside a closed contour labeled 100 ft → so D is >100 ft? But answer says 100 ft

Wait — D is on the 100 ft contour line? Or inside?

Looking at the map: The closed contour around D is labeled 100 ft, and D is inside it. So D is higher than 100 ft, but less than 110 ft (since next higher is 110). So 101–109 ft

But answer says 100 ft — again, incorrect unless D is on the line.

But the map shows D inside the 100 ft contour, so cannot be 100 ft.

So the given answers may have errors.

Let’s recheck all:

Corrected Elevations:

| Point | Location | Elevation |
|-------|----------|-----------|
| A | On 110 ft contour | 110 ft |
| G | On 180 ft contour | 180 ft |
| C | On 170 ft contour | 170 ft |
| F | On 110 ft contour | 110 ft |
| D | Inside 100 ft contour → so >100, <110 → 101–109 ft |

But the answer key says:
- A = 100 → ✘
- G = 180 → ✔ (if on line)
- C = 170 → ✔
- F = 110 → ✔
- D = 100 → ✘

So only A and D are wrong.

But why does it say A = 100?

Possibly misreading: Maybe the 110 label is not on the same line as A.

Wait — look at the map: There’s a blue line (river) flowing past A. The contour line labeled 110 is next to A, but is A on it?

Actually, A is on a contour line that is unlabeled, but the nearby labeled line is 110. The spacing suggests the contour interval is 10 ft, so the line A is on must be 110 ft.

So A = 110 ft

But the answer says 100 ft — this is incorrect.

Unless the contour lines are decreasing — but rivers flow downhill, and water flows from high to low, so the 110 ft line is higher than 100.

Wait — the river flows from higher to lower elevation. The contour lines bend upstream, showing that the land is higher on the sides.

But point A is on a 110 ft contour, so elevation = 110 ft

Therefore, the answer key has an error for A and D.

But let’s move on.

6. What is the highest possible elevation of point E?

Answer: 199 feet

✔ Explanation:
Point E is inside a closed contour labeled 190 ft. Since the contour interval is 10 ft, the next higher contour would be 200 ft. But there is no 200 ft contour around E, so the elevation at E must be less than 200 ft.

So maximum possible elevation is 199 ft.

✔️ Correct.

---

7. What is the lowest possible elevation of point M?

Answer: 161 feet

✔ Explanation:
Point M is inside a closed contour labeled 160 ft. Since it's a hilltop, it must be higher than 160 ft, so minimum elevation is 161 ft.

✔️ Correct.

---

8. What is a possible elevation of point J?

Answer: Any value from 111 to 119 feet

✔ Explanation:
Point J is located between the 110 ft and 120 ft contour lines. Since the contour interval is 10 ft, the elevation must be greater than 110 ft and less than 120 ft.

So possible values: 111 to 119 feet.

✔️ Correct.

Summary of Corrections:

| Question | Given Answer | Correct Answer | Notes |
|--------|--------------|----------------|-------|
| 5a (A) | 100 ft | 110 ft | A is on 110 ft contour |
| 5d (D) | 100 ft | 101–109 ft | D is inside 100 ft contour → >100 ft |
| Others | All correct | ✔️ | |
