is usa in south america or north america
North America The term North America maintains various definitions in accordance with location and context. In Canadian English, North America may be used to refer to the United States and Canada together.[11] Alternatively, usage sometimes includes Greenland[12][13][14] and Mexico (as in the North American Free Trade Agreement),[13][15][16][17][18] as well as offshore islands. The UN geoscheme for "North America" separates Mexico from the United States and Canada, placing it instead within its designated "Central America" region, while also treating the islands of the Caribbean separately from the US/Canada definitionâ€”the UN's "North America" definition still includes the Canadian Arctic Archipelago and Greenland together with the US/Canada continental definition, with both insular entities being tectonically on the North American plate.
