Where is elevation marked on a map?

• A. given along index contour lines (the heavy brown lines; every fifth line)
• B. along blue water features
• C. on the map margin only
• D. at the map corners

Answer: (B)

Elevation on a map is shown with contour lines that connect points of equal height. The numbers along the heavier index contour lines (the lines that stand out, often every fifth one) label the elevation of that line, making it easy to read the terrain at a glance. Water features drawn in blue show depth and flow, not height, so they don’t carry elevation values. Margins and corners don’t typically display elevation data either; the actual elevation readings come from the contour lines themselves, especially the labeled index contours.
