How is elevation indicated on a topographical map?

Elevation on a topographical map is indicated by contour lines. Contour lines are drawn to connect points of equal elevation on the map, providing a visual representation of the terrain's shape and relief. Each line represents a specific elevation level, and the spacing between these lines illustrates the steepness of the terrain; closely spaced lines indicate a steep slope, while widely spaced lines suggest a gradual incline.

By using contour lines, topographical maps allow users to understand the elevation changes in an area, making it easier to visualize hills, valleys, and other geographical features. Each contour line is typically labeled with its elevation, providing clear information on how high or low the land is at any given point.
