The Andes Mountains are the world’s longest continental Folded mountain range. They formed at a convergent boundary where the oceanic Nazca Plate subducts beneath the South American Plate. This compression, combined with significant volcanic activity, created the massive, elongated cordillera that runs along the western coast of South America, featuring extreme vertical relief. ANSWER: (A) Folded mountain
The Andes Mountains are an example of which type of mountain? (A) Folded mountain (B) Volcanic mountain (C) Residual mountain (D) Fault-block mountain

Geographically, the Andes are a prime example of an “Andean-type” Folded mountain range formed at an oceanic-continental plate boundary. While they contain many volcanic peaks, their primary structure is a result of the intense folding and crustal shortening caused by the subduction of the Nazca Plate. This tectonic pressure has uplifted the sedimentary and igneous rocks into a series of high ridges and internal plateaus. Stretching over 7,000 kilometers, the Andes influence the entire continent’s geography, creating a rain-shadow effect that results in the Atacama Desert to the west and the lush Amazon basin to the east.
