Explanation:

1. Contour lines on topographic maps are defined as lines connecting points with the same elevation.
2. Index contours are the bolded, labeled contour lines that help readers quickly reference elevation values on a topographic map.
3. The consistent vertical difference between adjacent contour lines is known as the contour interval.
