Topography and Geology of South America

Topographically the continent is divided into three sections-the South American cordillera, the interior lowlands, and the continental shield. The continental shield, in the east, which is separated into two unequal sections (the Guiana Highlands and the Brazilian Highlands) by the Amazon geosyncline, contains the continent’s oldest rocks.

Geologic studies in South America have supported the theory of continental drift and have shown that until 135 million years ago South America was joined to Africa; a Brazil-Gabon link has been established on the basis of tectonic matching.

Extending down the middle of the continent is a series of lowlands running southward from the llanos of the north, through the selva of the great Amazon basin and the Gran Chaco, to the Pampa of Argentina.

People of South America

Ethnic groups of South America include:
Awa
Banawa
Caiapos
Enxet
European descendants, especially from Spain, Portugal and Italy.
Ge
Guarani
Incas
Quechuas
Juris
Latin peoples
Mapuche
Mestizo
Xucuru
Zaparos

Indigenous peoples make up the majority of the population in Bolivia and Peru, and are a significant element in most other former Spanish colonies. Exceptions to this include Argentina and Uruguay. At least three of the Amerindian languages (Quechua in Peru and Bolivia, Aymara also in Bolivia, and Guarani in Paraguay) are recognized along with Spanish as national languages. Argentina is 10 percent Indian.

Mestizos

“Mestizo” is a term of Spanish origin used to designate the peoples of mixed European and Amerindian racial strain inhabiting the region spanning the Americas.

Mestizos officially make up the majority of the populations of Chile (90%), Colombia (58%), Ecuador (65%), Paraguay (95%) and Venezuela (67%). Figures in other countries are Argentina (about 13%), Bolivia (30%), Brazil (about 12%), Uruguay (8%) and Peru (37%).

African ancestry

Africans first arrived with the Spanish and Portuguese in the 16th century. Most were brought as slaves and delivered to Brazil and the Caribbean. Brazil now has about 60 million black people. Venezuela, Colombia, and Guyana also have significant black populations.

All the American and Caribbean countries have seen important contributions by Afro-Latin Americans. Historical research on this subject has become more and more prevalent during the last four decades.

“Mulato” is a term of Spanish origin (Mulatto in English) describing Latin Americans of mixed African and White racial descent.

“Zambo” is a term of Spanish origin describing Latin Americans of mixed African and Amerindian racial descent. The feminine form is zamba.

Culture of South America

Roman Catholicism is the dominant religion. French Guiana also has a large number of Protestants. Guyana and Suriname are exceptions, with three major religions: Christianity in general, Hinduism, and Islam.

Portuguese and Spanish are the primary languages of the continent. The majority of South Americans (51%) speak Portuguese. However, most South American countries are Spanish-speaking, and nearly all of the continent’s lusophones reside in Brazil.

Among other languages used by many South Americans are:
Aymara in Bolivia and Peru.
Quechua in Bolivia, Ecuador, and Peru.
Guarani in Paraguay.
English in Guyana.
Hindi in Guyana and Suriname.
Dutch and Indonesian in Suriname.
Italian and German in certain pockets across southern South America.

South American nations have a rich variety of music. Some of the most famous genres include samba from Brazil, tango from Argentina and cumbia from Colombia.

Because of South America’s ethnic mix, South American cuisine takes on African, American Indian, and European influences. Bahia, Brazil, is especially well-known for its West African-influenced cuisine.

Economy of South America

As of 2002, South America’s unemployment rate was 10.8 percent.

Due to histories of high inflation in nearly all South American countries, interest rates and thus investment remain high and low, respectively.

Interest rates are usually double that of the United States. For example, interest rates are about 22 percent in Venezuela and 23 percent in Suriname. The exception is Chile, which had a head start from 1973 under Augusto Pinochet.

The South American Community of Nations is a planned continent-wide free trade zone to unite two existing free-trade organizations-Mercosur and the Andean Community.

In South America, the gap between the rich and the poor is tremendous. In Venezuela, Paraguay, Brazil, and many other South American countries, the richest 20 percent may own over 60 percent of the nation’s wealth, while the poorest 20 percent may own less than 5 percent.

This wide gap can be seen in many large South American cities where makeshift shacks and slums lie next to skyscrapers and upper-class luxury apartments.

History of South America

South America is thought to have been first inhabited by people crossing the Bering Land Bridge, now the Bering strait, though there are also suggestions of migration from the southern Pacific Ocean.

Chavin

The Chavin established a trade network and developed agriculture by 900 BC, according to some estimates and archeological finds. Artifacts were found at a site called Chavin de Huantar in modern Peru at an elevation of 3,177 meters. Chavin civilization spanned 900 BC to 300 BC.

Inca

Holding their capital at the great city of Cusco, the Inca civilization dominated the Andes region from 1438 to 1533. Known as Tahuantinsuyu, or “the land of the four regions,” in Quechua, the Inca culture was highly distinct and developed. Cities were built with precise, unmatched stonework, constructed over many levels of mountain terrain. Terrace farming was a useful form of agriculture. There is evidence of excellent metalwork in Inca civilization.

European colonization

In 1494, Portugal and Spain, the two great maritime powers of that time, on the expectation of new lands being discovered in the west, signed the Treaty of Tordesillas, by which they agreed that all the land outside Europe should be an exclusive duopoly between the two countries.

The Treaty established an imaginary line along a north-south meridian 370 leagues west of Cape Verde Islands, roughly 46° 37′ W. In terms of the treaty, all land to the west of the line (which is now known to comprehend most of the South American soil), would belong to Spain, and all land to the east, to Portugal. As accurate measurements of longitude were impossible at that time, the line was not strictly enforced, resulting in a Portuguese expansion of Brazil across the meridian.

Beginning in the 1530s, the people and natural resources of South America were repeatedly exploited by foreign conquistadors, first from Spain and later from Portugal. These competing colonial nations claimed the land and resources as their own and divided it into colonies.

European diseases (smallpox, influenza, measles and typhus) to which the native populations had no resistance, and cruel systems of forced labor, such as the infamous haciendas and mining industry’s mita, decimated the American population under Spanish control. After this, African slaves, who had developed immunities to these diseases, were quickly brought in to replace them.

Geography of South America

The classification of its geographic location is subject to dispute, as in some non-English speaking regions of the world, the Americas are a continent and North, Central and South America are its subcontinents.

In English-speaking and certain other regions of the world, North and South America are considered to be continents and their union is referred to as the supercontinent of the Americas. The classification given to South America, as a subcontinent in a continent or a continent in a supercontinent, depends entirely on regional preferences.

It became attached to North America only recently (geologically speaking) with the formation of the Isthmus of Panama some 3 million years ago, which resulted in the Great American Interchange. The Andes, likewise a comparatively young and seismically restless mountain range, run down the western edge of the continent; the land to the east of the Andes is largely tropical rain forest, the vast Amazon River basin. The continent also contains drier regions such as Patagonia and the extremely arid Atacama desert.

Introducation of South America

South America is a continent situated in the Western Hemisphere between the Pacific and Atlantic Oceans. Most of it is in the Southern Hemisphere.

Commonly referred to as part of the Americas, like North America, South America is named after Amerigo Vespucci, who was the first European to suggest that the Americas were not the East Indies, but a previously undiscovered New World.

South America has an area of 17,820,000 km² (6,880,000 sq mi), or almost 3.5% of the Earth’s surface. As of 2005, its population was estimated at more than 371,200,000. South America ranks fourth in area (after Asia, Africa, and North America) and fifth in population (after Asia, Africa, Europe, and North America).

South America, the planet’s 4th largest continent, includes (12) countries and (3) major territories. The continent contains the Amazon River and rainforest, the Andes Mountains, and some of the most spectacular scenery on the planet.
