What is South American plate?
[[File:SouthAmericanPlate.png|thumb|250px|The South American plate]] The '''South American plate''' is a major [[tectonic plate]] which includes the [[continent]] of [[South America]]. It also includes part of the [[Atlantic Ocean]] seabed. This extends east to the [[African plate]]. They meet at the southern part of the [[Mid-Atlantic Ridge]]. The easterly edge is a [[divergent boundary]] because it has been moving west for about 60 million years. Its western and southern edges are complicated, with a number of small plates. The Nazca plate on the western edge is moving under the South American plate. This [[subduction]] has caused the [[Andes]] [[mountain chain]].
