Peru is a large country that is part of Western South America and borders the South Pacific Ocean. Peru consists of three regions stretched north to south. A dry coastal plain, called the Costa, lies in the west. The Andes Mountains or the Sierra lie in the center. The vast Amazon Rainforest is in the east. The Costa blends in with Chile’s Atacama Desert. However, the ocean next to it has plentiful fishing, cold waters, and small islands. The volcanic and earthquake prone Andes Mountains rise to snow capped peaks. Among them is the highest elevation in the country, Mount Huscarán, at 22, 205 feet. However, most of the central and western peaks are dry and brown. Peru’s longest rivers are tributaries of the Amazon, such as the Napo, Marañan, and Ucayali.
