Brazil is characterized by the extensive low-lying Amazon Rainforest in the
north and a more open terrain of hills and low mountains to the south and home
to most of the Brazilian population and its agricultural base. Along the
Atlantic seacoast are also found several mountain ranges, reaching roughly 2,900
metres (9,500 ft) high.
The highest peak is the 3,014 metre (9,735 ft) Pico da Neblina (Myst's
Peak) in Guiana's highlands. Major rivers include the Amazon, the largest river
in the world in flowing water volume, and the second-longest in the world; the
Paraná and its major tributary, the Iguaçu River, where the impressive Iguaçu
falls are located; the Negro, São Francisco, Xingu, Madeira and the Tapajós
rivers.
