On a terrain map, what do brown contour lines indicate?

• A. Elevation
• B. Water depth
• C. Vegetation
• D. Administrative boundaries

Answer: (A)

Contour lines on a terrain map are used to show elevation and the shape of the land. Each line connects points that sit at the same height above sea level, so you can read how high the ground is and how it rises or falls across the landscape. The brown color is the traditional choice for these elevation lines on many topographic maps, helping them stand out from other features. How close the lines are tells you about slope: tightly spaced lines mean steep terrain, while widely spaced lines indicate gentle slopes. If the lines form closed loops that rise toward the center, you’re looking at a hill or mountain; V-shaped patterns point upstream in valleys. Water depth is shown in blue, vegetation/or land cover is shown with different greens or browns, and administrative boundaries use other colors like red or purple. So the brown contour lines indicate elevation.
