What is happening to the plates in the Andes Mountains?
The Andes were formed by tectonic activity whereby earth is uplifted as one plate (oceanic crust) subducts under another plate (continental crust). To get such a high mountain chain in a subduction zone setting is unusual which adds to the importance of trying to figure out when and how it happened.
What causes earthquakes in the Andes?
Earthquakes are common in the Andes Mountains because they are near the boundary of two tectonic plates. These are the Nazca Plate and the South…

What are the Andes Mountains a result of?
Is Andes Mountains convergent or divergent?
The Andes is a mountain range found in South America. The Andes Mountains were formed at a convergent boundary between an oceanic plate and a…
What type of plates formed the Andes Mountains?
The mountains have been formed as a result of the convergence of the Nazca plate and the South American plate. The heavier oceanic crust of the Nazca plate is pushed towards the South American plate, and because it is denser is subducted underneath.
Why is Andes mountains important?
The Andes play a vital part in national economies, accounting for a significant proportion of the region’s GDP, providing large agricultural areas, mineral resources, and water for agriculture, hydroelectricity (Figure 1), domestic use, and some of the largest business centres in South America.
What type of mountain is the Andes?
Fold mountains are the most common type of mountain in the world. The rugged, soaring heights of the Himalayas, Andes, and Alps are all active fold mountains.
What was the main cause of the rise of the Andes?
The main cause of the rise of the Andes is the compression of the western rim of the South American Plate due to the subduction of the Nazca Plate and the Antarctic Plate.
Where are the Andes Mountains located in the world?
The Andes are a Mesozoic–Tertiary orogenic belt of mountains along the Pacific Ring of Fire, a zone of volcanic activity that encompasses the Pacific rim of the Americas as well as the Asia-Pacific region.
Where does the orientation of the Andes Mountains turn?
The Bolivian Orocline is a seaward concave bending in the coast of South America and the Andes Mountains at about 18° S. At this point, the orientation of the Andes turns from Northwest in Peru to South in Chile and Argentina.
How are the Andes mountains related to the Pacific Ring of fire?
The Andes are a Mesozoic – Tertiary orogenic belt of mountains along the Pacific Ring of Fire, a zone of volcanic activity that encompasses the Pacific rim of the Americas as well as the Asia-Pacific region. The Andes are the result of tectonic plate processes, caused by the subduction of oceanic crust beneath the South American Plate.
