Building Topographic Maps Lab 2.20.12
Part 1: Mapping a Mountain
1. What do lines of your map represent?
The lines represent the contour lines on a topographic map, which show difference in height.
2. The lines of a topographic mar are called contour lines. Use a highlighter and highlight ONE of the contour lines on your drawing.

3. What information do the contour lines give the map reader?
The lines show the elevation of a land feature, such as steepness or depressions.
4 Give an example of when someone might use a topographic map.
You might use a topographic map if you are hiking and you need a map. The contour lines will then show if there is a land feature, so you wouldn't plan to hike through it.

Part 2: Mapping the Mountain with a Stream
1. How was this map drawing different from the first map drawing?
There is an indention where the stream is, so a part of the line has a bump in it, which is like a valley.
2. What effect has the stream had on the mountain?
The stream erodes in the mountain.
3. What do you predict will happen as the stream continues to erode the mountain?
The stream will cut deeper into the mountain.
4. Based on your drawing, what would you look for in the contour lines of a topographic map to identify stream erosion of a land form?
You would look for a bump/indention on the contour lines.

Part 3: Mapping a Mountain with a River
1. How has the map drawing changed now?
The indention is deeper and the gap is wider.
2. What do contour lines that are close together indicate?
The lines that are close together represent steepness.
3. How has the river effected the mountain?
The river erodes the mountain more than the stream.
4. Predict what you think will happen if the river continues to erode the mountain.
The river will continue to erode the mountain.
5. How can a scientist use a topographic map to observe erosion changes in land forms over time?
The topographic maps can show how rivers and streams erode the mountain and cut into it.
