Which color on a map indicates vegetation such as woods and grassland?

The correct answer is green, as this color typically represents areas of vegetation on a map. Green is used universally in cartography to signify natural features such as forests, parks, and grasslands, making it easy for map readers to identify locations that are covered with plant life.

Brown generally denotes terrain features like contour lines and elevation changes, blue represents bodies of water such as rivers and lakes, and red often indicates man-made structures or important roads. Thus, green is specifically chosen to symbolize vegetation and helps users quickly recognize areas where plant life is present.
