Question 1

True or false: The Andes are the longest continental mountain range in the world.

Accepted Answer

True. Stretching over 7,000 km along South America's western edge, the Andes surpass any other continental range in length, including the Himalayas.

Question 2

True or false: The highest peak in the Andes is Mount Aconcagua, which is also the tallest mountain outside Asia.

Accepted Answer

True. Aconcagua reaches 6,961 meters, making it the highest in the Western and Southern Hemispheres, second only to Himalayan peaks globally.

Question 3

True or false: The Amazon River originates directly from the highest peaks of the Peruvian Andes.

Accepted Answer

False. The Amazon's source is in the Peruvian Andes but not the highest peaks. Its farthest source is the Apurímac River headwaters on Nevado Mismi (approx. 5,597 m), while Peru's highest peak is Huascarán (6,768 m).

Question 4

True or false: The Andes are home to the world's largest salt flat, Salar de Uyuni, which is visible from space.

Accepted Answer

True. Salar de Uyuni in Bolivia spans over 10,000 square kilometers, formed by prehistoric lakes, and its bright white crust is seen from orbit.

Question 5

True or false: The Andes have more than 100 active volcanoes, making them the most volcanically active mountain range on Earth.

Accepted Answer

True. The range hosts about 200 volcanoes, with over 100 active, due to the subduction of the Nazca Plate beneath the South American Plate.

Question 6

True or false: The Andes have no major cities located above 4,000 meters in elevation.

Accepted Answer

False. El Alto, Bolivia, a major city with over 800,000 people, sits at approximately 4,150 meters, disproving the statement.

Question 7

True or false: The Andes are home to the world’s largest glacier outside the polar regions.

Accepted Answer

False. The largest glacier outside polar regions is the Fedchenko Glacier in Tajikistan, not in the Andes. The Patagonian Ice Fields, though in the Andes, are ice fields, not a single glacier.

Question 8

True or false: The Andes were formed by the collision of two continental plates, similar to the Himalayas.

Accepted Answer

False. The Andes formed from oceanic-continental subduction, not continental collision. The Nazca Plate sinks under South America, uplifting the range.
