Geography of Brazil Brazil occupies a large portion of eastern South America and shares borders with Argentina, Bolivia, Colombia, French Guiana, Guyana, Paraguay, Peru, Suriname, Uruguay and Venezuela; its territory includes the Fernando de Noronha archipelago and extends from the equatorial Atlantic coast to the shores of the Río de la Plata basin, encompassing diverse landforms such as the Amazon Basin, the Brazilian Highlands and the Pantanal. The country's spatial extent shapes interactions with regional bodies like the Union of South American Nations and continental features such as the Andes Mountains and maritime zones governed under the United Nations Convention on the Law of the Sea.

Location and Extent

Brazil spans roughly 8.5 million square kilometres between about 5°N and 34°S latitude and between 35°W and 74°W longitude, making it the largest country in South America and the fifth-largest in the world, bordering ten sovereign states including Argentina and Colombia while facing the Atlantic Ocean opposite island groups such as the Azores and continental neighbors along the South Atlantic Ocean. Its exclusive economic zone and continental shelf are managed alongside regional agreements involving Argentina–Brazil maritime boundary considerations and institutions like the Brazilian Navy and the International Hydrographic Organization. Brazil's continental extremities—Monte Caburaí in Roraima, Ponta do Seixas in Paraíba, Cape Orange in Amapá, and Chuí in Rio Grande do Sul—anchor political divisions such as Amazonas and Rio Grande do Sul.

Physical Geography and Major Landforms

Topography ranges from the low-lying Amazon Basin—drained by the Amazon River—to the eroded plateaus of the Brazilian Highlands and crystalline shields like the Guiana Shield and the Congo Craton equivalent in South America; prominent features include the Serra do Mar coastal range, the tepuis of Roraima and the escarpments of the Planalto Central. Geological history links to events recorded in the Precambrian and processes related to the breakup of Pangaea and the opening of the South Atlantic Ocean, leaving rock provinces such as the Craton cores and mineralized belts exploited in regions like Minas Gerais and Carajás Mineral Province. Coastal geomorphology features barrier islands near Recife and high cliffs at Vila Velha, while inland wetlands include the Pantanal—shared with Bolivia and Paraguay—and upland river plateaus in Mato Grosso.

Climate and Biomes

Brazil exhibits climatic zones from equatorial climate in Amazonas and Roraima to tropical savanna climate in the Cerrado and semi-arid climate in the Northeast such as Caatinga, extending to subtropical climate in Rio Grande do Sul; meteorological patterns are influenced by the Intertropical Convergence Zone, the South Atlantic High and the El Niño–Southern Oscillation. Major biomes include the Amazon rainforest—the largest tropical forest on Earth—alongside the Cerrado, Atlantic Forest, Caatinga, Pampas, and Pantanal, each hosting endemic genera catalogued by institutions like the Brazilian Institute of Environment and Renewable Natural Resources and studies conducted at universities such as the University of São Paulo and Federal University of Amazonas.

Hydrology and River Systems

Brazil's river network is dominated by the Amazon River system—the largest by discharge—fed by tributaries such as the Rio Negro, Madeira River, Tapajós River and Xingu River; western drainage links to the Amazon Basin while southern systems include the Paraná River with its tributaries Paraguay River and Tietê River, and the Río de la Plata basin shared with Argentina. Hydropower infrastructure includes projects on the Itaipu Dam between Brazil and Paraguay, the Balbina Dam and transmission networks serving urban centres like São Paulo and Rio de Janeiro; riverine navigation, floodplain ecology and sediment transport affect ports such as Belém and Manaus, and conservation efforts involve agencies like the Chico Mendes Institute for Biodiversity Conservation.

Regional Divisions and States

Brazil is a federation of 26 states and the Federal District where Brasília is located; major states include São Paulo, Rio de Janeiro, Bahia, Paraná, Minas Gerais and Amazonas, grouped into five geographic regions—North, Northeast, Central-West, Southeast and South—defined by the Brazilian Institute of Geography and Statistics. Regional disparities manifest in urban agglomerations like the São Paulo metropolitan area, historic port cities such as Salvador and industrial corridors near Belo Horizonte, with transportation arteries including the BR-101 and BR-116 highways and airports like São Paulo–Guarulhos International Airport and Galeão International Airport.

Natural Resources and Environmental Issues

Brazil's endowment includes iron ore in Minas Gerais, nickel and gold in Amazonas, bauxite in Pará, and vast timber and biodiversity in the Amazon rainforest; petroleum and LNG production occur offshore in basins like the Campos Basin near Rio de Janeiro, managed by companies such as Petrobras. Environmental challenges encompass deforestation driven by agribusiness in the Matopiba region, habitat loss in the Atlantic Forest, wetlands conversion in the Pantanal, pollution incidents affecting estuaries near Santos, São Paulo, and governance debates involving the Ministry of the Environment (Brazil), international agreements like the Paris Agreement, and NGOs including Greenpeace and the World Wide Fund for Nature. Conservation responses involve protected areas such as the Jaú National Park and sustainable initiatives promoted by research centres like the National Institute for Space Research (INPE).
