A composite relief satellite image of South America, the fourth-largest continent. South America occupies the southern portion of the landmass in the Western Hemisphere. The continent is generally delimited on the northwest by the Darién watershed along the Colombia–Panama border. Almost all of mainland South America sits on the South American Plate, as do nearby outlying islands. Photo: Blue Marble by Reto Stockli, NASA/GSFC |
