What feature of this continent is described by the different colors on the map

Answer/Explanation

Physical maps use color to show changes in elevation.

A palette of greens often displays elevations. Dark green usually represents low-lying land, with lighter shades of green used for higher elevations. In the next higher elevations, physical maps often use a palette of light brown to dark brown. Such maps commonly use reds, white, or purples to represent the highest elevations shown on the map. Blues are used for water, with darker blues representing the deepest water. Green-gray, red, blue-gray, are used for elevations below sea level.
