World map, Definition, History, Challenges, & Facts

A world map is a graphical representation that depicts Earth’s exterior on a flat surface. World maps can be used to show political features, such as borders between states, as well as physical features. Because Earth is an ellipsoid, a world map is necessarily a distorted representation that various transformations, called projections, have attempted to moderate. World maps have evolved over time to gradually include all regions of Earth.
