Topographic Map Worksheet Answer Key Pdf - Fill Online, Printable ... - Free Printable

Since I can't view or access images directly, I can't see the specific topographic map you've uploaded. However, I can help you solve the problems if you provide a description of the map or the details from the image, such as:

- The location and elevation of key points (A, B, C, D, etc.)
- The contour interval (you mentioned 50 feet)
- The position of Philadelphia Lake
- The direction of streams and hills
- Any labeled features like lakes, peaks, or trails

But based on your worksheet and typical topographic map questions, here’s how to approach each question in general, assuming standard topographic map conventions:

---

Question 1: Is the creek flowing over or out of Philadelphia Lake?

How to determine:
- Look at the contour lines around the lake.
- If the creek flows out of the lake, the stream will flow downhill from the lake toward lower elevations.
- On a topo map, streams flow downhill, so they exit the lake where the contours show a drop in elevation.

✔ Answer:
If the stream exits the lake and flows downhill (i.e., contours slope away from the lake), then it is flowing out of Philadelphia Lake.

> ✔ *Typically, lakes are at higher elevations than streams that flow from them. So if the stream is exiting the lake into lower ground, it's flowing out.*

Question 2: You are standing at point A. What is your height above sea level?

How to determine:
- Find the contour line closest to point A.
- Use the contour interval (50 ft) to calculate elevation.
- If point A is on a contour line, its elevation is that value.
- If between two lines, estimate halfway (e.g., 300 ft if between 250 and 300).

✔ Example:
If point A is on the 400-ft contour line → 400 ft above sea level.

> ⚠️ *Make sure to check if there's an index contour (thicker line) with a number for accuracy.*

Question 3: Describe the relief or topography of the land between you and the lake.

How to determine:
- Look at the spacing of contour lines:
- Close together = steep slope
- Far apart = gentle slope
- Circular contours = hill or depression
- If you're at point B and looking toward the lake, describe whether the land slopes up or down.

✔ Answer Example:
"The land slopes gently downward from point B toward Philadelphia Lake. The contour lines are widely spaced, indicating a gradual descent."

Question 4: Are you gaining elevation, losing elevation, or remaining level when walking south from B to C?

How to determine:
- Check the elevation values along the path.
- If you go from a higher to lower contour line → descending.
- If you go from lower to higher → ascending.
- If same elevation → flat.

✔ Answer Example:
"If contour lines increase in elevation from B to C, you are gaining elevation."

Question 5: Could you hike from point E to Lake ET?

How to determine:
- Look at the topography between E and Lake ET.
- Check if there’s a ridge, valley, or cliff blocking the path.
- If the terrain is not too steep and there’s a passable route, yes.

✔ Answer Example:
"Yes, you could hike from E to Lake ET because the contour lines suggest a gentle slope and no significant obstacles."

---

Question 6: Are you going up a steep hill, going down a valley, or going up a gully from B to D?

How to determine:
- Look at the contour pattern:
- Contour lines close together and bending upward → steep hill
- Lines forming a "V" pointing uphill → valley
- Lines forming a "V" pointing downhill → ridge
- Gully = small valley, often with a stream

✔ Answer Example:
"If the contour lines form a V pointing toward B, and you're moving toward D, you're going down a valley."

📌 Summary Tips:

- Contour Interval: 50 ft → each line = 50 ft change in elevation.
- Stream flow: Always follows the lowest path (downhill).
- Hills: Contours form closed loops, increasing inward.
- Valleys/Gullies: Contours form Vs pointing upstream.
- Ridges: Contours form Vs pointing downhill.
