What do contour lines on a map denote?

• A. Categories of vegetation
• B. Imaginary lines representing elevation
• C. Boundaries of property
• D. Locations of military bases

Answer: (B)

Contour lines on a map represent elevation by connecting points of equal height above a specific reference level, usually sea level. These lines indicate the shape and steepness of the terrain, allowing users to visualize the landscape in three dimensions. When closely spaced, contour lines indicate steep slopes, while widely spaced lines suggest gentle slopes. Understanding contour lines is crucial for navigation, planning construction, and assessing the terrain for various purposes, such as military operations or environmental studies. This knowledge is fundamental for anyone working with topographic maps, as it helps interpret the land's features effectively.
