What measures distances at the bottom of a map?

• A. Bar scale
• B. Grid
• C. Scale bar
• D. Legend

Answer: (A)

Distances on a map are read using a graphic scale. The scale bar, a bar-like ruler at the bottom of the map, shows real-world units corresponding to the map distances. By lining up or comparing the distance between two points on the map with the marks on the scale bar, you can read off how far apart they are in reality. This visual ruler is designed specifically to translate map units into ground distances quickly and directly. In contrast, a grid helps you locate positions, and a legend explains map symbols, but neither provides a direct distance measurement like the scale bar does.
