What are the lines on a topographic map that show land elevation called?

• A. Contour Lines
• B. Elevation Lines
• C. Contour Maps
• D. Altitude Lines

Answer: (A)

Elevation on a topographic map is shown by contour lines, which connect all points at the same height above sea level. They reveal the shape of the terrain—closely spaced lines mean steep slopes, while lines that are farther apart indicate gentler slopes. Each contour line represents a specific elevation, and maps often label some lines for quick reference. Contour line is the standard term for these features; the other phrases aren’t commonly used in this context. So the lines that show land elevation are contour lines.
