Quiz Answer Key and Fun Facts

1. Let's start with an easy one: which South American river is the most voluminous (in terms of water content) river in the world?

Answer: Amazon River

The Amazon, or Amazon River, also forms the world's largest drainage basin, constituting about one-fifth of the world's total river flow. The Amazon River basin extends from 5 degrees north to 20 degrees south latitude. The Amazon River also accounts for twenty percent of the world's fresh water discharged into oceans.

2. The name of which river, one of the Amazon's major tributaries, means "black river" in Spanish and Portuguese?

Answer: Rio Negro

Rio Negro, the world's largest blackwater river, floods heavily during the rainy season, reaching a width of up to nineteen miles. Part of the Rio Negro forms part of the boundary between Colombia and Venezuela. The banks of Rio Negro, whose Native American population declined during the 17th century, support nonetheless a large fishing industry.

3. Which city, known as the "Heart of the Amazon" and "City of the Forest," is the capital of the Brazilian state of Amazonas?

Answer: Manaus

Manaus, founded in 1669, owes its growth and development in the 19th century to the extraction of rubber from the Amazon forest. During the rubber boom, Manaus was one of the most corrupt and decadent cities in the New World. The profligacy featured an Opera House that cost the Brazilian public ten million dollars to build. During the boom, Manaus' rubber barons competed to outdo one another in extravagance. Today, timber, petroleum refining, and ecotourism are among the city's most important industries. Manaus is home to the Free Economic Zone of Manaus, which is politically and economically autonomous within Brazil.

4. Sharks have been reported 2,500 miles up the Amazon River at Iquitos, Peru.

Answer: true

The bull shark, a marine shark that can migrate into and live in freshwater, is cited in these reports. The bull shark's ability to swim back and forth between fresh and salt water has mystified scientists for years. There are no known occasions, however, of bull sharks reproducing in fresh water.

5. Which of the following rivers forms part of the border between Uruguay and Argentina?

Answer: Rio de la Plata

The banks of the Rio de la Plata are among the most densely populated regions of Argentina and Uruguay. The Rio de la Plata Basin is the second largest of South America. It includes parts of Argentina, Brazil, Bolivia, Paraguay, and Uruguay.

6. Which lake on the border between Bolivia and Peru, which by volume of water is the largest lake in South America, is fed by five river systems?

Answer: Lake Titicaca

The river systems that feed into Lake Titicaca are the Ramis, Coata, Llave, Huancane, and Suchez. Additionally, the lake has 41 islands, including the Islas del Sol and de la Luna featured in Inca mythology.

Answer: Orinoco River

The boto, or Amazon River dolphin, a pink river dolphin, dwells both in the Amazon and the Orinoco Rivers. The Orinoco is linked to the Amazon by the Casiquiare canal, which connects the Orinoco to Rio Negro, one of the Amazon's major tributaries.

8. Which is the second longest river in South America?

Answer: Parana River

The Parana River runs through Brazil, Paraguay, and Argentina. The Itaipu Dam, the second largest hydroelectric power station in the world, is located on the Parana River on the border between Brazil and Paraguay.

9. Which river, located in eastern Brazil, was "discovered" by Amerigo Vespucci on Oct 4, 1501, who named it after a saint whose feast day falls on October 4?

Answer: Sao Francisco River

The Sao Francisco River, the fourth longest in South America and the longest to lie completely in Brazil, is particularly important in Brazilian folklore. Stories of monsters and demons residing in the river circulate in eastern Brazil until today.

10. Which river in Chile shares its name with the tallest mountain in South America?

Answer: Aconcagua River

Despite the river's and mountain's shared name, the slopes of Mount Aconcagua and the source of the Aconcagua River are geographically separated. Mount Aconcagua is in Argentina while the Aconcagua River is created by two joining tributaries, the Juncal and the Blanco, in the Chilean Andes. The river feeds into the Pacific Ocean north of Valparaiso, Chile.
