The Südamerikanische Platte (South American Plate) is a tectonic plate that covers most of South America and parts of the Atlantic Ocean. It is bordered by several other plates, including the Nazca Plate to the west, which is responsible for the Andes mountain range's formation due to subduction. This plate is significant in understanding geological activity in the region, including earthquakes and volcanic eruptions. The movement of the Südamerikanische Platte affects the surrounding areas, influencing the landscape and ecosystems, such as the Amazon Rainforest and the Andes Mountains.
