UPSC CSE Prelims 2024

Correct Option (B):

The information provided in rows 3 and 4 is correctly matched.

• North America-Appalachians-Fold mountain: The Appalachian Mountains, located in eastern North America, are indeed ancient Fold Mountains, formed during the Paleozoic Era.
• South America-Andes-Fold mountain: The Andes Mountains, extending along the western coast of South America, are Young Fold Mountains, formed primarily by the subduction of the Nazca Plate under the South American Plate.

Incorrect Options:

• Central Asia-Vosges-Fold mountain: This is incorrect. The Vosges Mountains are located in Europe (primarily France and Germany), not Central Asia. Furthermore, they are classified as Block Mountains, not Fold Mountains.
• Europe-Alps-Block mountain: This is incorrect. The Alps, a major mountain range in Europe, are classic examples of Young Fold Mountains, formed by the collision of the African and Eurasian tectonic plates. They are not Block Mountains.

Therefore, only two of the given rows (3 and 4) contain correctly matched information.
