The South American plate is a major tectonic plate which includes the continent of South America as well as a sizable region of the Atlantic Ocean seabed extending eastward to the African plate, with which it forms the southern part of the Mid-Atlantic Ridge.
Scotia plate – Minor oceanic tectonic plate between the Antarctic and South American plates – 1,600,000 km 2 (620,000 sq mi) Somali plate – Minor tectonic plate including the east coast of Africa and the adjoining seabed – 16,700,000 km 2 (6,400,000 sq mi)

The oceanic Nazca plate subducts beneath the continental South American plate at the Peru–Chile Trench. Just north of the Nazca plate, the oceanic Cocos plate subducts under the Caribbean plate and forms the Middle America Trench. Oceanic crust of the South American plate subducts under the Caribbean plate in the Lesser Antilles subduction zone.
The Bouvet triple junction is a geologic triple junction of three tectonic plates located on the seafloor of the South Atlantic Ocean. It is named after Bouvet Island, which lies about 250 km (160 mi) to the east. [2] The three plates which meet here are the South American plate, the African plate, and the Antarctic plate.
The Río de la Plata basin (Spanish: Cuenca del Plata, Portuguese: Bacia do Prata), more often called the River Plate basin in scholarly writings, [1] sometimes called the Platine basin [2] or Platine region, [3] is the 3,170,000-square-kilometre (1,220,000 sq mi) [4] hydrographical area in South America that drains to the Río de la Plata.
Here three tectonic plates meet: the South American plate, the Nazca plate and the Antarctic plate. This triple junction is unusual in that it consists of a mid-oceanic ridge, the Chile Rise, being subducted under the South American plate at the Peru–Chile Trench. The Chile triple junction is the boundary between the Chilean Rise and the ...
[20] [21] Almost all of mainland South America sits on the South American Plate. South America is home to several superlatives, including the world's highest uninterrupted waterfall, Angel Falls in Venezuela; the highest single-drop waterfall Kaieteur Falls in Guyana; the largest river by volume, the Amazon River; the longest mountain range ...
