You will learn to use topographic maps to visualize natural land features and man-made features.
After completing this tutorial, you will be able to complete the following:
1. For what purposes do we use maps?
~ We commonly use maps to illustrate the layout and features of a certain area of land.
2. What is a topographic map?
~ A topographic map is a type of map that shows both natural land features (like mountains and hills) and man-made features (like roads and buildings) from the top view, detailing their heights.
3. What is the baseline height of all topographic maps?
~ The baseline height of all topographic maps is sea level, which is labeled as zero meters.
4. How are the varying heights of a natural land feature represented on a topographic map?
~ The varying heights of a natural land feature are represented on a topographic map with contour lines, which serve to connect and detail points of equal heights.
5. What does the frequency of contour lines indicate about the change in height of a natural land feature?
~ The frequency of contour lines is an indication of how steeply inclined, or how level, a natural land feature is. In other words, the closer together the contour lines, the steeper the land feature is.
