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, home to most of Brazil's population and its agricultural base. Along the coast of the Atlantic Ocean are also found several mountain ranges, which can reach roughly 2,900m high. However, the highest peak is the Pico da Neblina at 3,014 m, in Guiana's highlands. Major rivers include the Amazon, the largest river in the world by volume, and considered by many specialists also the longest of the world; the Paraná and its major tributary, the Iguaçu River, where the impressive Iguaçu falls are located; the Rio Negro, São Francisco, Xingu, Madeira and the Tapajós rivers.
Situated along the equator, Brazil's climate is predominantly tropical, with little seasonal variation, though the subtropical south is more temperate and can occasionally experience frost and snow. Precipitation is abundant in the humid Amazon Basin, though more arid landscapes are found as well, in particular in the northeast.
