Where is the contour interval amount given?

• A. in the marginal information
• B. in the title block
• C. in the legend
• D. along the boundary lines

Answer: (C)

Contour interval is the vertical distance between adjacent contour lines, which tells you how much elevation changes from one line to the next. This essential reading aid is provided in the legend, the map’s reference key that explains symbols, line types, and numerical values used on the map. Having the interval in the legend lets you quickly interpret elevations across the map without searching elsewhere. The other areas—marginal information, title block, and boundary lines—serve different purposes: marginal information may include scale and coordinates, the title block shows the map name and date, and boundary lines indicate edges, not the spacing of elevation lines.
