Which color is used to depict relief on maps?

• A. Green
• B. Blue
• C. Black
• D. Brown

Answer: (D)

Relief shows the shape and height of the land, and mapmakers use color ramps so you can read terrain at a glance. Blue represents water, green typically marks lower elevations or vegetation, and brown is used to convey higher elevations and the steep, rugged relief of hills and mountains. The brown shading emphasizes elevation changes and contrasts nicely with green and blue, making mountains and plateaus easy to spot. That’s why brown is the color most commonly used to depict relief. Green isn’t used for high ground, blue signals water, and black is usually reserved for text, boundaries, or contour lines rather than the shading of terrain.
