Question: 1 / 400

What is the purpose of contour lines on a map?

To indicate man-made structures

To show the elevation and relief of the terrain

Contour lines on a map serve the essential purpose of depicting the elevation and relief of the terrain. These lines connect points of equal elevation, allowing a user to visualize the steepness and shape of the land. When contour lines are close together, they reflect a steep slope, while lines that are spaced further apart indicate gentler slopes. This information is crucial for navigation, planning routes, and understanding the geography of an area, particularly in mountainous or hilly regions.

Understanding elevation and terrain relief is vital for various activities, such as hiking, military maneuvers, and construction planning, as it influences decisions regarding travel routes, positioning of resources, and determining potential obstacles. Additionally, contour lines can help identify landforms such as hills, valleys, and ridges.
