UPSC IAS – 2024
1. Central Asia, Vosges, Fold mountain: The Vosges Mountains are located in Western Europe (France/Germany), not Central Asia. They are primarily block mountains formed by faulting, not fold mountains, although they have experienced complex geological history. This row is incorrectly matched.
2. Europe, Alps, Block mountain: The Alps are located in Europe. They are classic examples of young fold mountains formed by the collision of the African and Eurasian tectonic plates. They are not block mountains. This row is incorrectly matched.
3. North America, Appalachians, Fold mountain: The Appalachian Mountains are located in eastern North America. They are ancient fold mountains formed by past continental collisions. This row is correctly matched.
4. South America, Andes, Fold mountain: The Andes Mountains are located along the western coast of South America. They are young fold mountains formed by the subduction of the Nazca Plate under the South American Plate. This row is correctly matched.
Therefore, two rows (3 and 4) are correctly matched.
– Block mountains are formed by faulting and uplifting or down-dropping of blocks of crust (e.g., Vosges, Black Forest, Sierra Nevada).
