Which color on a topographic map typically represents elevation changes?

On a topographic map, brown is the color that represents elevation changes. This is because brown is commonly used to depict contour lines, which connect points of equal elevation. These contour lines illustrate the terrain's relief, allowing users to visualize how steep or flat an area is and to determine the heights of hills, mountains, and valleys. Elevation data presented in brown helps those using the map to navigate the landscape effectively, whether for recreational activities, planning, or rescue operations.

The other colors on a topographic map serve different purposes: red or orange typically represent roads or urban development, green is often used to denote vegetation or agricultural areas, and pink may indicate certain types of land use or administrative boundaries. Understanding the specific uses of these colors is essential for interpreting the topographic features accurately.
