What do contour lines on a map represent?

Contour lines on a map represent points of equal elevation, which means that any location along a contour line is at the same height above sea level. This allows map readers to visualize the terrain and understand features such as hills, valleys, and slopes. By observing how close or far apart the contour lines are, one can infer the steepness of the terrain—closer lines indicate a steeper slope, while wider spacing signifies a gentler incline.

In topographic maps, these lines give crucial information for activities such as hiking, urban planning, and environmental management, where understanding the elevation changes and landforms is essential. Each contour line typically indicates a specific elevation value, enabling users to easily assess the landscape’s characteristics and navigate more effectively.
