South America features diverse landforms, including the towering Andes Mountains, which stretch along the western edge of the continent. These mountains are the longest continental mountain range in the world and are home to many unique ecosystems and wildlife. In addition to the Andes, the continent boasts vast plains like the Pampas in Argentina and the Amazon Basin, which is the largest rainforest on Earth. The Amazon River, flowing through this basin, is one of the longest rivers globally, supporting a rich variety of flora and fauna.
