Greatest Rio

Rio de Janeiro is on a strip of Brazil's Atlantic coast, close to the Tropic of Capricorn, where the shoreline is oriented east–west. Facing largely south, the city was founded on an inlet of this stretch of the coast, Guanabara Bay (Baía de Guanabara), and its entrance is marked by a point of land called Sugar Loaf (Pão de Açúcar) – a "calling card" of the city. The Centre (Centro), the core of Rio, lies on the plains of the western shore of Guanabara Bay. The greater portion of the city, commonly referred to as the North Zone (Zona Norte), extends to the northwest on plains composed of marine and continental sediments and on hills and several rocky mountains. The South Zone (Zona Sul) of the city, reaching the beaches fringing the open sea, is cut off from the Centre and from the North Zone by coastal mountains. These mountains and hills are offshoots of the Serra do Mar to the northwest, the ancient gneiss-granite mountain chain that forms the southern slopes of the Brazilian Highlands. The large West Zone (Zona Oeste), long cut off by the mountainous terrain, had been made accessible by new roads and tunnels by the end of the 20th century. The population of the city of Rio de Janeiro, occupying an area of 1,182.3 square kilometres (456.5 sq mi), is about 6,000,000. The population of the greater metropolitan area is estimated at 11–13.5 million. It was Brazil's capital until 1960, when Brasília took its place. Residents of the city are known as cariocas. The official song of Rio is "Cidade Maravilhosa", by composer André Filho. own by Tamarion Johnson.
