To describe how elevation is shown on a topographic map, you can follow these steps:

1. Locate the map key or legend: The map key or legend is a section of the map that provides explanations for the symbols and colors used. Look for symbols or colors that represent contour lines or elevation.

2. Identify contour lines: Contour lines on a topographic map depict lines of equal elevation. They connect points that have the same height above a reference point, such as sea level. Each contour line represents a specific elevation value.

3. Understand contour interval: Contour intervals indicate the vertical distance between adjacent contour lines. For example, if the contour interval is 10 meters, each contour line represents a difference of 10 meters in elevation.

4. Determine elevation: To determine the elevation of a specific point on the map, locate the nearest contour line and read its value. Suppose the contour lines are labeled every 50 meters, and the point of interest is in between two contour lines. You can estimate the elevation based on the contour interval.

5. Interpret contour lines: By analyzing the spacing, shape, and pattern of contour lines, you can identify features on the map such as hills, valleys, cliffs, and ridges. Close contour lines indicate steep slopes, while widely spaced lines suggest gentle slopes.

By following these steps and examining the map's key and contour lines, you can describe how elevation is shown on a topographic map.
