What is the role of a legend on a map?

The role of a legend on a map is to explain the symbols used on the map. A legend, often found in a corner of the map, provides crucial information by defining what various symbols and colors represent. This aids in the interpretation of the map, allowing users to understand features such as roads, landmarks, elevations, and other geographic elements. Without a legend, a map can be confusing, as the symbols may not be intuitive.

The other options describe important aspects of a map but do not pertain to the function of a legend. For example, the scale of the map relates to the distance represented on the map in relation to actual distances on the earth. The illustration of physical features concerns the topography and landscape details presented on the map, while orientation indicates the direction (such as north) to help users navigate the layout of the depicted area. These elements enhance the utility of a map but serve different purposes than the legend itself.
