Problem Analysis:
The image provided is a
topographic map, which uses contour lines to represent the shape and elevation of the terrain. The task involves analyzing the map and answering questions about its features.
---
Solution:
####
1. There are squiggly lines all over this map. What are they called?
-
Answer: The squiggly lines on the map are called
contour lines.
-
Explanation: Contour lines are lines that connect points of equal elevation on a topographic map. They help visualize the three-dimensional shape of the land in two dimensions.
---
####
2. Some of these lines have numbers written on them. What do those numbers mean?
-
Answer: The numbers written on the contour lines represent the
elevation (in feet or meters) above sea level.
-
Explanation: Each contour line is labeled with a specific elevation value, indicating the height of the land at that point. For example, a line labeled "12000" means that the elevation at that point is 12,000 feet above sea level.

####
3. What does it mean when those lines are close together?
-
Answer: When contour lines are close together, it indicates a
steep slope.
-
Explanation: The distance between contour lines represents the change in elevation over a given horizontal distance. If the lines are close together, the elevation changes rapidly over a short horizontal distance, which corresponds to a steep slope.
---
####
4. What does it mean when those lines are spread far apart?
-
Answer: When contour lines are spread far apart, it indicates a
gentle slope.
-
Explanation: If the contour lines are spaced widely apart, the elevation changes slowly over a larger horizontal distance, which corresponds to a gentle or gradual slope.

Final Answers:
1.
Contour lines
2.
Elevation (in feet or meters)
3.
Steep slope
4.
Gentle slope

Boxed Final Answer:
\[
\boxed{
\begin{array}{l}
1. \text{Contour lines} \\
2. \text{Elevation (in feet or meters)} \\
3. \text{Steep slope} \\
4. \text{Gentle slope}
\end{array}
}
\]
