Brazil occupies a large area along the eastern coast of South America. Brazil is the fifth largest country in the world, after Russia, Canada, China and the United States, and third largest in the America; with a total area of 8,514,876.599 square kilometers, including 55,455 square kilometers of water. It spans three time zones; from UTC-4 in the western states, to UTC-3 in the eastern states (and the official time of Brazil) and UTC-2 in the Atlantic islands.
Brazilian topography is also diverse and includes hills, mountains, plains, highlands, and scrublands. Much of the terrain lies between 200 metres and 800 metres in elevation. The main upland area occupies most of the southern half of the country. The northwestern parts of the plateau consist of broad, rolling terrain broken by low, rounded hills.
The southeastern section is more rugged, with a complex mass of ridges and mountain ranges reaching elevations of up to 1,200 metres. These ranges include the Mantiqueira and Espinhaço Mountains and the Serra do Mar. In the north, the Guiana Highlands form a major drainage divide, separating rivers that flow south into the Amazon Basin from rivers that empty into the Orinoco River system, in Venezuela, to the north. The highest point in Brazil is the Pico da Neblina at 2,994 metres, and the lowest is the Atlantic Ocean.
Brazil has a dense and complex system of rivers, one of the world's most extensive, with eight major drainage basins, all of which drain into the Atlantic. Major rivers include the Amazon (the world's second-longest river and the largest in terms of volume of water), the Paraná and its major tributary the Iguaçu (which includes the Iguazu Falls), the Negro, São Francisco, Xingu, Madeira and Tapajós rivers.
