2. Physical Geography The Big Idea
The physical geography of Atlantic South America includes large river systems, plains and plateaus, and the Amazon rain forest.
Main Ideas
Physical features of Atlantic South America include large rivers, plateaus, and plains.
Climate and vegetation in the region ranges from cool, dry plains to warm, humid forests.
The rain forest is a major source of natural resources.

3. Main Idea 1: Physical features of Atlantic South America include large rivers, plateaus, and plains.
Atlantic South America includes Brazil, Argentina, Uruguay, and Paraguay.
This region covers two-thirds of South America.
Brazil occupies almost half of the continent.

4. Major River Systems Amazon River World’s largest river system
Flows eastward across northern Brazil through Peru to Atlantic Ocean
4,000 miles long
Carries more water than any other river: 20 percent of Earth’s surface water
Lowers the salt level of the Atlantic Ocean for more than 100 miles
Río de la Plata
Paraná River flows into Río de la Plata and the Atlantic Ocean.
Paraná River drains central part of South America.
Río de la Plata is an estuary, or a partially enclosed body of water where freshwater mixes with salty sea water.

5. Plains and Plateaus
The land of South America is mostly plains and plateaus.
The Amazon Basin in northern Brazil is a giant floodplain.
The Brazilian Highlands are rugged, old, eroded mountains and a high plain area called the Mato Grosso Plateau.
Farther south are the low plains known as Gran Chaco.
Argentina is home to the wide, grassy plains of the Pampas and the dry plains and plateaus of Patagonia.
All these plains rise in the west to form the high Andes Mountains.

6. Main Idea 2: Climate and vegetation in the region ranges from cool, dry plains to warm, humid forests.
Cool climates in southern and highland areas
Tropical climates in the northern and coastal areas
General
Climate
Patagonia has a cool, desert climate.
Rich soils in humid subtropical Pampas are good for farming.
In Gran Chaco, summer rains can turn these humid, tropical plains into marshlands.
Argentina
Central region is tropical savanna climate with grasslands.
Amazon Basin’s tropical climate in northern Brazil supports the world’s largest rain forest.

7. Main Idea 3: The rain forest is a major source of natural resources.
Amazon rain forest provides food, wood, rubber, plants for medicines, and other products.
Deforestation, or the clearing of trees, has become a problem.
Near coastal areas, the land supports commercial farming.
Planting the same crop every year has caused soil exhaustion, which means the soil is infertile because it has lost nutrients needed by plants.
Other resources: gold, silver, copper, iron, and oil
Dams provide hydroelectric power.

8. Brazil
The Big Idea
The influence of Brazil’s history can be seen all over the country in its people and culture.
Main Ideas
Brazil’s history has been affected by Brazilian Indians, Portuguese settlers, and enslaved Africans.
Brazil’s society reflects a mix of people and cultures.
Brazil today is experiencing population growth in its cities and new development in rain forest areas.

9. Main Idea 1: Brazil’s history has been affected by Brazilian Indians, Portuguese settlers, and enslaved Africans.
Colonial Brazil
First people: American Indians arrived many thousands of years ago and hunted, fished, and farmed.
1500: Portuguese explorers arrived.
Colonists brought in Africans to work as slaves on sugar plantations.
Colonists established cattle ranches inland.
In late 1600s and early 1700s: People discovered gold and gems.
Late 1800s: Brazil began producing coffee.
Since Independence
1822: Brazil won independence from Portugal without war.
Economy did not change and slavery continued.
Brazil has been ruled by dictators and elected officials.
Today, Brazil has an elected president and legislature.
Brazil is the largest country in South America.
It has 186 million people—more than all the other countries combined.

10. Main Idea 2: Brazil’s society reflects a mix of people and cultures.
More than half of people are descended from Portugal, Spain, Germany, Italy, or Poland.
Nearly 40 percent are of mixed African and European descent.
Brazil has the largest Japanese population outside Japan.
Official language: Portuguese.
Others speak Spanish, English, French, Japanese, or native languages.

11. Brazil About 70 percent are Roman Catholic.
Protestantism is growing in popularity among urban poor.
Some practice macumba, a religion that combines African, Brazilian, Indian, and Christian beliefs and practices.
Religion
Brazilians celebrate Carnival before Lent.
Carnival mixes African, native, and European traditions.
E.g., the samba adapted from Africa
Cultural mix can be found in foods: vatapá, an African seafood dish, and feijoada, a black bean and meat stew.

12. Main Idea 3: Brazil today is experiencing population growth in its cities and new development in rain forest areas.
The Southeast
Most people live in the southeast.
São Paulo,
Largest urban center in South America; 5th largest in the world
A megacity, a giant urban area that includes surrounding cities and suburbs
Rio de Janeiro
Second largest city in Brazil
Capital from
Richest region: industries and good farmland
Poor people come to the cities for work.
They live in huge slums called favelas.

13. The Northeast Brazil’s poorest region
Illiteracy and health care are a problem.
Droughts make farming and raising livestock difficult.
Region’s beautiful beaches attract tourists.
Old colonial cities also attract tourists.
These were built during the days of the sugar industry.
They feature brightly painted buildings, cobblestone streets, and churches.

14. The Interior and the Amazon
The interior is a frontier.
Mild climate and land may make it good for farming in the future.
Brasilia, Brazil’s capital
More than 2 million people
Built to help develop interior
Modern buildings and busy highways
The Amazon
Manaus
Major port and industrial city
More than 1 million people
Indian villages are scattered throughout the rain forest.
Indians had little contact with outsiders until recently.
Logging, mining, and new roads are bringing more people.
This development brings income, but destroys the rain forest.

15. Argentina, Uruguay, and Paraguay
The Big Idea
Argentina, Uruguay, and Paraguay have been influenced by European immigration, a tradition of ranching, and large urban populations.
Main Ideas
European immigrants have dominated the history and culture of Argentina.

17. Modern Argentina
New immigrants arrived from Italy, Germany, and Spain.
British helped build railroads that made it easier to transport agricultural products such as beef for export.

Home to most of Argentina’s industry
Its location near coast and Pampas has contributed to its economic development.
Pampas
Most developed agricultural region
