Regents Earth Science Topographic Profiles Practice Answer Key ... - Free Printable

Since I can't view or access uploaded images directly, I can’t see the specific topographic map you’re referring to. However, I can guide you through how to solve the types of questions typically found on a Regents Earth Science Topographic Profile Practice worksheet based on standard topographic map principles.

Let’s go step by step and explain how to answer each question assuming a typical contour map like the one described:

---

1. What is the contour interval of this map?

How to find it:
- Look at two adjacent contour lines and note their elevation values.
- Subtract the lower elevation from the higher one.
- The difference is the contour interval.

Example:
If one line is labeled 700 ft and the next is 720 ft, then:
> Contour Interval = 720 - 700 = 20 feet

✔ Answer: The contour interval is usually printed on the map or can be calculated by finding the difference between two labeled contours.

2. What is the highest elevation? ________ Lowest elevation? ________

How to find it:
- Highest elevation: Look for the innermost closed contour line (usually a hilltop). The elevation is the value of that line. If there's a hachure mark (short lines), it might indicate a depression.
- Lowest elevation: Find the outermost contour line or the lowest labeled contour near the edge of the map.

Example:
- Innermost contour: 800 ft → Highest elevation = 800 ft
- Outermost contour: 600 ft → Lowest elevation = 600 ft

✔ Answer:
- Highest elevation: ___ ft
- Lowest elevation: ___ ft

*(You’ll need to read the labels on your map.)*

3. Measure the distance in CENTIMETERS from point A to point B.

How to do it:
- Use a ruler to measure the straight-line distance between points A and B on the map.
- Record the measurement in centimeters.

✔ Answer: Example: 5.2 cm

---

4. Convert this distance into MILES using the scale provided.

Use the map scale:
The scale bar shows that 1 inch = 10 miles, or sometimes it's given in centimeters.

But in your image, the scale is shown as:

```
0 2 4 6 8 10 miles
```

This means:
- 2 inches = 2 miles
- So, 1 inch = 1 mile
- But since we're measuring in centimeters, we must convert.

Wait — let's assume the scale bar is in centimeters.

But the scale says:
`0 2 4 6 8 10 miles` with tick marks — so likely each 2 cm = 2 miles, meaning:

> 1 cm = 1 mile

So if the distance from A to B is 5.2 cm, then:

> Distance in miles = 5.2 × 1 = 5.2 miles

✔ Answer: 5.2 miles

---

5. Repeat the procedure for points C to D.

Same steps:
- Measure distance in cm from C to D → say, 3.5 cm
- Multiply by scale factor (1 cm = 1 mile)
- So, 3.5 cm = 3.5 miles

✔ Answer:
CM Distance: 3.5 cm
MILES: 3.5 miles

---

✔ Final Answers (Example Based on Typical Map):

1. Contour interval: 20 feet
2. Highest elevation: 800 ft
Lowest elevation: 600 ft
3. Distance A to B (cm): 5.2 cm
4. Distance A to B (miles): 5.2 miles
5. C to D (cm): 3.5 cm
C to D (miles): 3.5 miles

---

⚠️ Note: These answers depend on your actual map. You must:
- Read the contour labels,
- Measure distances accurately with a ruler,
- Use the scale correctly.

If you can describe the map (e.g., “the contour lines go from 600 to 800 in steps of 20,” or “A to B is about 6 cm”), I can give exact answers.

Would you like to describe the map details so I can help you get the correct numbers?
