South America occupies the southern portion

South America occupies the southern portion of the landmass referred to as the Western Hemisphere. The continent is generally delimited on the northwest by the Darién watershed along the Colombia–Panama border, or (according to some sources) by the Panama Canal which transects the Isthmus of Panama. Geopolitically and geographically[4] all of Panama – including the segment east of the Panama Canal in the isthmus – is typically included in North America alone[5][6][7] and among the countries of Central America.[8][9] Almost all of mainland South America sits on the South American Plate. South America's triangular shape gives it the shortest coastline, for its size, of any of the continents.
