The earliest pottery ever found in the Western Hemisphere was excavated in the Amazon basin of Brazil and radiocarbon dated to 8,000 years ago (6000 BC). The pottery was found near Santarém and provides evidence that the region supported a complex prehistoric culture. The Marajoara culture flourished on Marajó in
9856-455: The arrival of the Portuguese fleet commanded by Pedro Álvares Cabral . The Portuguese encountered indigenous peoples divided into several ethnic societies, most of whom spoke languages of the Tupi–Guarani family and fought among themselves. Though the first settlement was founded in 1532, colonization effectively began in 1534, when King John III of Portugal divided the territory into
9984-468: The atmosphere over the oceans, keeping the British Isles and northwestern Europe mild and cloudy, and not severely cold in winter, like other locations at the same high latitude. The cold water currents contribute to heavy fog off the coast of eastern Canada (the Grand Banks of Newfoundland area) and Africa's northwestern coast. In general, winds transport moisture and air over land areas. Every winter,
10112-458: The cancellation of the 1938 election and formalized Vargas as dictator, beginning the Estado Novo era. During this period, government brutality and censorship of the press increased. During World War II , Brazil remained neutral until August 1942, when the country suffered retaliation by Nazi Germany and Fascist Italy in a strategic dispute over the South Atlantic, and, therefore, entered
10240-502: The central power, coupled with old and latent social tensions peculiar to a vast, slaveholding and newly independent nation state . This period of internal political and social upheaval, which included the Praieira revolt in Pernambuco , was overcome only at the end of the 1840s, years after the end of the regency, which occurred with the premature coronation of Pedro II in 1841. During
10368-617: The continent except Ecuador and Chile . Brazil's Amazon basin includes a vast tropical forest home to diverse wildlife , a variety of ecological systems , and extensive natural resources spanning numerous protected habitats . This unique environmental heritage positions Brazil at number one of 17 megadiverse countries . The country's natural richness is also the subject of significant global interest, as environmental degradation (through processes such as deforestation ) has direct impacts on global issues such as climate change and biodiversity loss . The territory of present-day Brazil
10496-418: The continent's interior, sharing land borders with Uruguay to the south; Argentina and Paraguay to the southwest; Bolivia and Peru to the west; Colombia to the northwest; and Venezuela , Guyana , Suriname and France (French overseas region of French Guiana ) to the north. It shares a border with every South American country except Ecuador and Chile . The brazilian territory also encompasses
10624-584: The demands of revolutionaries who had taken the city of Porto , John VI departed for Lisbon. There he swore an oath to the new constitution, leaving his son, Prince Pedro de Alcântara , as Regent of the Kingdom of Brazil . Tensions between Portuguese and Brazilians increased and the Portuguese Cortes , guided by the new political regime imposed by the Liberal Revolution , tried to re-establish Brazil as
10752-644: The east, and the Americas to the west. As one component of the interconnected World Ocean , it is connected in the north to the Arctic Ocean , to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south. Other definitions describe the Atlantic as extending southward to Antarctica . The Atlantic Ocean is divided in two parts, the northern and southern Atlantic, by
10880-596: The east, the boundaries of the ocean proper are Europe: the Strait of Gibraltar (where it connects with the Mediterranean Sea – one of its marginal seas – and, in turn, the Black Sea , both of which also touch upon Asia) and Africa. In the southeast, the Atlantic merges into the Indian Ocean. The 20° East meridian , running south from Cape Agulhas to Antarctica defines its border. In
11008-544: The eastern and western North Atlantic central water since the western part is strongly affected by the Gulf Stream and therefore the upper layer is closer to underlying fresher subpolar intermediate water. The eastern water is saltier because of its proximity to Mediterranean water. North Atlantic central water flows into South Atlantic central water at 15°N . There are five intermediate waters: four low-salinity waters formed at subpolar latitudes and one high-salinity formed through evaporation. Arctic intermediate water flows from
11136-471: The enactment of the Amnesty Law in 1979, Brazil began a slow return to democracy , which was completed during the 1980s. Civilians returned to power in 1985 when José Sarney assumed the presidency. He became unpopular during his tenure through failure to control the economic crisis and hyperinflation he inherited from the military regime. Sarney's unsuccessful government led to the election in 1989 of
11264-608: The fifteen private and autonomous captaincies . However, the decentralized and unorganized tendencies of the captaincies proved problematic, and in 1549 the Portuguese king restructured them into the Governorate General of Brazil in the city of Salvador , which became the capital of a single and centralized Portuguese colony in South America. In the first two centuries of colonization, Indigenous and European groups lived in constant war, establishing opportunistic alliances in order to gain advantages against each other. By
11392-430: The first known humans to cross the Atlantic, it was the expedition of Christopher Columbus in 1492 that proved to be the most consequential. Columbus' expedition ushered in an age of exploration and colonization of the Americas by European powers , most notably Portugal , Spain , France , and the United Kingdom . From the 16th to 19th centuries, the Atlantic Ocean was the center of both an eponymous slave trade and
11520-452: The first time, "a drought has covered all the way from the North to the country’s Southeast". It is the strongest drought in Brazil since the beginning of measurement in the 1950s, covering almost 60% of the country's territory. The drought is linked to deforestation and climate change. Brazilian topography is also diverse and includes hills, mountains, plains, highlands, and scrublands. Much of
11648-459: The highest areas. The semiarid climatic region generally receives less than 800 millimeters (31.5 in) of rain, most of which generally falls in a period of three to five months of the year and occasionally less than this, creating long periods of drought. Brazil's 1877–78 Grande Seca (Great Drought), the worst in Brazil's history, caused approximately half a million deaths. A similarly devastating drought occurred in 1915. In 2024, for
11776-456: The largest war effort in Brazilian history. Although there was no desire among the majority of Brazilians to change the country's form of government , on 15 November 1889, in disagreement with the majority of the Imperial Army officers, as well as with rural and financial elites (for different reasons), the monarchy was overthrown by a military coup. A few days later, the national flag
11904-566: The last phase of the monarchy, internal political debate centered on the issue of slavery. The Atlantic slave trade was abandoned in 1850, as a result of the British Aberdeen Act and the Eusébio de Queirós Law , but only in May 1888, after a long process of internal mobilization and debate for an ethical and legal dismantling of slavery in the country , was the institution formally abolished with
12032-510: The latter 2,000 km (1,200 mi). Ocean currents such as the Gulf Stream transport eel larvae from the Sargasso Sea to foraging areas in North America, Europe, and northern Africa. Recent but disputed research suggests that eels possibly use Earth's magnetic field to navigate through the ocean both as larvae and as adults. The climate is influenced by the temperatures of the surface waters and water currents as well as winds. Because of
12160-645: The limits of the oceans and seas in 1953, but some of these definitions have been revised since then and some are not recognized by various authorities, institutions, and countries, for example the CIA World Factbook . Correspondingly, the extent and number of oceans and seas vary. The Atlantic Ocean is bounded on the west by North and South America. It connects to the Arctic Ocean through the Denmark Strait , Greenland Sea , Norwegian Sea and Barents Sea . To
12288-492: The lowest values are in the high latitudes and along coasts where large rivers enter. Maximum salinity values occur at about 25° north and south , in subtropical regions with low rainfall and high evaporation. The high surface salinity in the Atlantic, on which the Atlantic thermohaline circulation is dependent, is maintained by two processes: the Agulhas Leakage/Rings , which brings salty Indian Ocean waters into
12416-508: The margins of the continents constitute about 11% of the bottom topography with few deep channels cut across the continental rise. The mean depth between 60°N and 60°S is 3,730 m (12,240 ft), or close to the average for the global ocean, with a modal depth between 4,000 and 5,000 m (13,000 and 16,000 ft). In the South Atlantic the Walvis Ridge and Rio Grande Rise form barriers to ocean currents. The Laurentian Abyss
12544-635: The maximum depth, the Milwaukee Deep in the Puerto Rico Trench , is 8,376 m (27,480 ft). Top large seas: The bathymetry of the Atlantic is dominated by a submarine mountain range called the Mid-Atlantic Ridge (MAR). It runs from 87°N or 300 km (190 mi) south of the North Pole to the subantarctic Bouvet Island at 54°S . Expeditions to explore the bathymertry of
12672-561: The mid-16th century, cane sugar had become Brazil's most important export, while slaves purchased in Sub-Saharan Africa in the slave market of Western Africa (not only those from Portuguese allies of their colonies in Angola and Mozambique ), had become its largest import, to cope with sugarcane plantations , due to increasing international demand for Brazilian sugar. Brazil received more than 2.8 million slaves from Africa between
12800-718: The most extensive and voluminous large igneous provinces in Earth's history associated with the Triassic–Jurassic extinction event , one of Earth's major extinction events . Theoliitic dikes , sills , and lava flows from the CAMP eruption at 200 Ma have been found in West Africa, eastern North America, and northern South America. The extent of the volcanism has been estimated to 4.5 × 10 km (1.7 × 10 sq mi) of which 2.5 × 10 km (9.7 × 10 sq mi) covered what
12928-465: The naturally regenerating forest, 44% was reported to be primary forest (consisting of native tree species with no clearly visible indications of human activity) and around 30% of the forest area was found within protected areas. For 2015, 56.% of the forest area was reported to be under public ownership and 44% private ownership . Many regions have starkly different microclimates . An equatorial climate characterizes much of northern Brazil. There
13056-483: The new capital city of Brasília , inaugurated in 1960. Kubitschek's successor, Jânio Quadros , resigned in 1961 less than a year after taking office. His vice-president, João Goulart , assumed the presidency, but aroused strong political opposition and was deposed in April 1964 by a coup that resulted in a military dictatorship . The new regime was intended to be transitory but gradually closed in on itself and became
13184-439: The north and semiarid deserts in the northeast, to temperate coniferous forests in the south and tropical savannas in central Brazil. In Brazil, forest cover is around 59% of the total land area, equivalent to 496,619,600 hectares (ha) of forest in 2020, down from 588,898,000 hectares (ha) in 1990. In 2020, naturally regenerating forest covered 485,396,000 hectares (ha) and planted forest covered 11,223,600 hectares (ha). Of
13312-563: The north to become the source for North Atlantic deep water, south of the Greenland-Scotland sill. These two intermediate waters have different salinity in the western and eastern basins. The wide range of salinities in the North Atlantic is caused by the asymmetry of the northern subtropical gyre and a large number of contributions from a wide range of sources: Labrador Sea, Norwegian-Greenland Sea, Mediterranean, and South Atlantic Intermediate Water. The North Atlantic deep water (NADW)
13440-464: The northern, northeastern regions and in the Cisplatina province. The last Portuguese soldiers surrendered on 8 March 1824; Portugal officially recognized Brazilian independence on 29 August 1825. On 7 April 1831, worn down by years of administrative turmoil and political dissent with both liberal and conservative sides of politics, including an attempt of republican secession and unreconciled to
13568-425: The ocean's great capacity to store and release heat, maritime climates are more moderate and have less extreme seasonal variations than inland climates. Precipitation can be approximated from coastal weather data and air temperature from water temperatures. The oceans are the major source of atmospheric moisture that is obtained through evaporation. Climatic zones vary with latitude; the warmest zones stretch across
13696-611: The outlines of the coasts of the Old and the New Worlds. The remainder of the ridge was discovered in the 1920s by the German Meteor expedition using echo-sounding equipment. The exploration of the MAR in the 1950s led to the general acceptance of seafloor spreading and plate tectonics . Most of the MAR runs under water but where it reaches the surfaces it has produced volcanic islands. While nine of these have collectively been nominated
13824-521: The political establishment and public service , numerous peaceful protests erupted in Brazil in the middle of the first term of Dilma Rousseff , who had succeeded Lula after winning election in 2010 and again in 2014 by narrow margins. Rousseff was impeached by the Brazilian Congress in 2016, halfway into her second term, and replaced by her Vice-president Michel Temer , who assumed full presidential powers after Rousseff's impeachment
13952-637: The pond" or "on the other side of the pond" or "across the pond", rather than to discuss the ocean itself. The term dates to 1640, first appearing in print in a pamphlet released during the reign of Charles I , and reproduced in 1869 in Nehemiah Wallington 's Historical Notices of Events Occurring Chiefly in The Reign of Charles I , where "great Pond" is used in reference to the Atlantic Ocean by Francis Windebank , Charles I's Secretary of State . The International Hydrographic Organization (IHO) defined
14080-438: The seafloor. The oldest oceanic crust in the Atlantic is up to 145 million years and is situated off the west coast of Africa and the east coast of North America, or on either side of the South Atlantic. In many places, the continental shelf and continental slope are covered in thick sedimentary layers. For instance, on the North American side of the ocean, large carbonate deposits formed in warm shallow waters such as Florida and
14208-688: The state of Acre and the westernmost portion of Amazonas , to UTC−4 in the western states, to UTC−3 in the eastern states (the national time ) and UTC−2 in the Atlantic islands . The climate of Brazil comprises a wide range of weather conditions across a large area and varied topography, but most of the country is tropical. According to the Köppen system , Brazil hosts six major climatic subtypes: desert , equatorial , tropical , semiarid , oceanic and subtropical . The different climatic conditions produce environments ranging from equatorial rainforests in
14336-534: The subtropics to the northeastern Atlantic. There this water is cooled during winter and forms return currents that merge along the eastern continental slope of Greenland where they form an intense (40–50 Sv ) current which flows around the continental margins of the Labrador Sea . A third of this water becomes part of the deep portion of the North Atlantic Deep Water (NADW). The NADW, in turn, feeds
14464-421: The surface is usually covered with sea ice in the Labrador Sea , Denmark Strait , and Baltic Sea. The Coriolis effect circulates North Atlantic water in a clockwise direction, whereas South Atlantic water circulates counter-clockwise. The south tides in the Atlantic Ocean are semi-diurnal; that is, two high tides occur every 24 lunar hours. In latitudes above 40° North some east–west oscillation, known as
14592-445: The terrain lies between 200 meters (660 ft) and 800 meters (2,600 ft) 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 meters (3,900 ft). These ranges include
14720-428: The total volume of the Earth's oceans. Excluding its marginal seas, the Atlantic covers 81,760,000 km (31,570,000 sq mi) and has a volume of 305,811,900 km (73,368,200 cu mi). The North Atlantic covers 41,490,000 km (16,020,000 sq mi) (11.5%) and the South Atlantic 40,270,000 km (15,550,000 sq mi) (11.1%). The average depth is 3,646 m (11,962 ft) and
14848-617: The upper layers of the circumpolar region, near the Drake Passage and the Falkland Islands. Both these currents receive some contribution from the Indian Ocean. On the African east coast, the small cyclonic Angola Gyre lies embedded in the large subtropical gyre. The southern subtropical gyre is partly masked by a wind-induced Ekman layer . The residence time of the gyre is 4.4–8.5 years. North Atlantic Deep Water flows southward below
14976-522: The wake of the murder of his running mate, the defeated opposition presidential candidate Getúlio Vargas , supported by most of the military, successfully led the Revolution of 1930 . Vargas and the military were supposed to assume power temporarily, but instead closed down Congress, extinguished the Constitution, ruled with emergency powers and replaced the states' governors with his own supporters. In
15104-630: The war on the allied side . In addition to its participation in the battle of the Atlantic , Brazil also sent an expeditionary force to fight in the Italian campaign . With the Allied victory in 1945 and the end of the fascist regimes in Europe, Vargas's position became unsustainable, and he was swiftly overthrown in another military coup, with democracy "reinstated" by the same army that had ended it 15 years earlier. Vargas committed suicide in August 1954 amid
15232-470: The way that absolutists in Portugal had given in the succession of King John VI, Pedro I departed for Portugal to reclaim his daughter's crown after abdicating the Brazilian throne in favor of his five-year-old son and heir (Dom Pedro II ). As the new Emperor could not exert his constitutional powers until he came of age, a regency was set up by the National Assembly. In the absence of
15360-424: The western Atlantic and South Sandwich Trench (8,264 m or 27,113 ft) in the South Atlantic. There are numerous submarine canyons off northeastern North America, western Europe, and northwestern Africa. Some of these canyons extend along the continental rises and farther into the abyssal plains as deep-sea channels. In 1922, a historic moment in cartography and oceanography occurred. The USS Stewart used
15488-518: The word brasil commonly given the etymology "red like an ember ", formed from brasa ('ember') and the suffix -il (from -iculum or -ilium ). It has alternatively been suggested that this is a folk etymology for a word for the plant related to an Arabic or Asian word for a red plant. As brazilwood produces a deep red dye, it was highly valued by the European textile industry and was the earliest commercially exploited product from Brazil. Throughout
15616-701: The years 1500 and 1800. By the end of the 17th century, sugarcane exports began to decline and the discovery of gold by bandeirantes in the 1690s would become the new backbone of the colony's economy, fostering a gold rush which attracted thousands of new settlers to Brazil from Portugal and all Portuguese colonies around the world. This increased level of immigration in turn caused some conflicts between newcomers and old settlers. Portuguese expeditions known as bandeiras gradually expanded Brazil's original colonial frontiers in South America to its approximately current borders. In this era other European powers tried to colonize parts of Brazil, in incursions that
15744-499: Was a status more won over time than assigned in succession ceremonies and conventions. Slavery among the indigenous groups had a different meaning than it had for Europeans, since it originated from a diverse socioeconomic organization, in which asymmetries were translated into kinship relations. Following the 1494 Treaty of Tordesillas , the land now called Brazil was claimed for the Portuguese Empire on 22 April 1500, with
15872-498: Was accepted on 31 August. Large street protests for and against her took place during the impeachment process. The charges against her were fueled by political and economic crises along with evidence of involvement with politicians from all the primary political parties. In 2017, the Supreme Court requested the investigation of 71 Brazilian lawmakers and nine ministers of President Michel Temer 's cabinet who were allegedly linked to
16000-485: Was applied to the southern Atlantic as late as the mid-19th century. During the Age of Discovery , the Atlantic was also known to English cartographers as the Great Western Ocean . The pond is a term often used by British and American speakers in reference to the northern Atlantic Ocean, as a form of meiosis , or ironic understatement. It is used mostly when referring to events or circumstances "on this side of
16128-430: Was in first place in the first round, with 48.43% of the support from the electorate, and received 50.90% of the votes in the second round. On 8 January 2023, a week after Lula's inauguration, a mob of Bolsonaro's supporters attacked Brazil's federal government buildings in the capital, Brasília , after several weeks of unrest. Brazil occupies a large area along the eastern coast of South America and includes much of
16256-408: Was inhabited by numerous tribal nations prior to the landing of explorer Pedro Álvares Cabral in 1500. Subsequently claimed by the Portuguese Empire , Brazil remained a Portuguese colony until 1808, when the capital of the empire was transferred from Lisbon to Rio de Janeiro . In 1815, the colony was elevated to the rank of kingdom upon the formation of the United Kingdom of Portugal, Brazil and
16384-488: Was replaced with a new design that included the national motto " Ordem e Progresso ", influenced by positivism . 15 November is now Republic Day , a national holiday. The early republican government was a military dictatorship, with the army dominating affairs both in Rio de Janeiro and in the states. Freedom of the press disappeared and elections were controlled by those in power. Not until 1894, following an economic crisis and
