RAS question
The Andes is the longest mountain range in the world, located in:
Correct answer: (A) South America (7,000 km).
The Andes are the world's longest continental mountain range and are located in South America.
Explanation
The answer is South America because Guinness World Records identifies the Andes, in South America, as the world's longest continental range of mountains. Guinness World Records gives the range as 7,600 kilometres long and says it spans seven countries; the commonly rounded exam figure is 7,000 km, with the range running along South America's western coast. Two exam-relevant anchors matter here: Aconcagua, at 6,961 m, is the highest peak, and the range formed through the subduction of the Nazca Plate beneath the South American Plate. So this is not just a continent-label fact; it links the Andes to South America and to active plate-margin mountain building.
Why the other options are wrong
- (B) Europe is wrong because the Andes are in South America, not on the European landmass.
- (C) Africa is wrong because the Andes are identified with South America, not Africa.
- (D) Asia is wrong because the Andes belong to South America, not Asia.
Concept
This tests world physical geography: major mountain ranges, their continental location, length and tectonic setting. It recurs in RAS because such one-line location facts often connect map work with plate-tectonics concepts.
