What type of scale allows for non-numeric communication of distance on a map?

The correct answer is the verbal scale, which communicates distance using words instead of numbers. A verbal scale typically states the relationship between distance on the map and distance on the ground in a descriptive format, such as "1 inch equals 1 mile" or "1 centimeter represents 10 kilometers." This type of scale is particularly useful because it is easily understood by the map reader regardless of their familiarity with numerical scales or measurement systems.

In contrast, a graphic scale (or bar scale) uses a visual representation, typically a line marked to indicate distance measurements, which can be measured alongside the map. While these scales can be useful for measuring distances at a glance, they still rely on numerical expressions of distance. A bar scale can also fit into a more numeric framework if the markings are read in standard distance measurements.

Overall, the verbal scale is the unique choice in this scenario that emphasizes an easy-to-understand, non-numeric method for conveying distances on a map, making it the best answer.
