The western part of Brazil is composed of the Brazilian Highlands, which is a vast region of plateaus and mountains. These highlands are formed by ancient crystalline rocks and have an average elevation of around 300 to 900 meters (984 to 2,953 feet). The highest point in Brazil, Pico da Neblina (2,994 meters or 9,822 feet), is located in the Brazilian Highlands, specifically in the Serra do Imeri mountains.
In contrast, the eastern part of Brazil is characterized by the Atlantic Coastal Plain, which is a relatively low-lying region with an average elevation of less than 200 meters (656 feet). This region is composed of sedimentary rocks and is home to several major cities, including Rio de Janeiro and São Paulo.
