What is a Legend on a map or chart?

• A. A list that identifies patterns, symbols, or colors used in a chart.
• B. The scale used to measure distances on a map.
• C. A computer program for geographic analysis.
• D. A set of statistical tables for demographics.

Answer: (A)

A legend on a map or chart is the key that explains what the symbols, colors, and patterns represent. By listing each symbol with its meaning, the legend lets you read the map accurately. For instance, a blue line might stand for a river, shaded green areas could indicate parks, and red dots might mark towns. Without this guide, the symbols wouldn’t tell you much about the features shown. The scale tells how distance on the map relates to real-world distance. A computer program for geographic analysis is software used to work with spatial data. A set of statistical tables for demographics is data you might study separately, not how the map’s symbols are interpreted. So the option that describes a list identifying patterns, symbols, or colors used in the chart is the best choice.
