A type of scale that has a line subdivided into map distances corresponding to convenient units of length on the ground is called

• A. A verbal scale
• B. A ratio scale
• C. A circular scale
• D. A graphic scale

Answer: (D)

Graphic scale is a line on a map that is subdivided into units of ground distance. This lets you measure distances directly on the map with a ruler because the length along the scale bar corresponds to real-world distances. It’s different from verbal scales, which state distances in words (for example, one inch equals a certain number of miles), and from ratio scales, which express the proportional relationship numerically without a drawn bar. It’s also not a circular scale, which uses a wheel or ring to show distance. The graphic scale provides a quick, visual way to convert map measurements to actual ground distances, making it especially practical for fieldwork and quick distance checks.
