Relief Brazil is a predominantly tropical country famous for its extensive Amazon lowlands; however, highlands cover most of the national territory. Brazil’s physical features can be grouped into five main physiographic divisions: the Guiana Highlands in the North, the Amazon lowlands, the Pantanal in the Central-West, the Brazilian Highlands (including the extensive coastal ranges), and the coastal lowlands.
The Amazon lowlands are widest along the eastern base of the Andes. Separates the Guiana Highlands to the north from the Brazilian Highlands to the south. he vбrzeas fan out again as the watercourse approaches the Atlantic, but no delta extends into the ocean. The basin’s most widespread topographical features are gently undulating hills called terra firme (“solid ground”), composed of layers of alluvial soil that were deposited as much as 2.5 million years ago and subsequently uplifted to positions above flood level. Shallow oxbow lakes and wetlands are found throughout the region.
Climate of Brazil Brazil has a humid tropical and subtropical climate except for a drier area in the Northeast, sometimes called the drought quadrilateral or drought polygon, that extends from northern Bahia to the coast between Natal and Sгo Luнs; that zone receives about 15–30 inches (375–750 mm) of precipitation a year. Much of Brazil receives 40–70 inches (1,000–1,800 mm) annually, but precipitation often is much heavier in parts of the Amazon basin and the sea-facing rim of the Serra do Mar.
