Are the Andes Mountains convergent boundary?
The Andes Mountains are part of the Southern Cordillera formed from subduction zone volcanism at the convergent boundary of the Nazca plate and the South American plate.
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…
Which plate boundary is between the Nazca and South American plates?
The Nazca Plate is bounded on the west by the Pacific Plate and to the south by the Antarctic Plate through the East Pacific Rise and the Chile Rise respectively….

What type of boundary is the Nazca and South American plate?
convergent boundaries
Examples of ocean-continent convergent boundaries are subduction of the Nazca Plate under South America (which has created the Andes Range) and subduction of the Juan de Fuca Plate under North America (creating the mountains Garibaldi, Baker, St.
Is the Antarctic Plate oceanic or continental?
The Antarctic Plate includes continental crust making up Antarctica and its continental shelf, along with oceanic crust beneath the seas surrounding Antarctica.
What type of plate boundary is North American and Eurasian plates?
The westerly side is a divergent boundary with the North American Plate forming the northernmost part of the Mid-Atlantic Ridge, which is straddled by Iceland….

What kind of plate boundary is the Antarctic Plate?
divergent plate
Today, about 95\% of the Antarctic plate is surrounded by divergent plate boundaries: the Southwest Indian Ridge, the Southeast Indian Ridge, and the American-Antarctica Ridge.
What type of plate boundaries Antarctic and Australian plates?
The southerly side is a divergent boundary with the Antarctic Plate called the Southeast Indian Ridge (SEIR). The subducting boundary through Indonesia is not parallel to the biogeographical Wallace line that separates the indigenous fauna of Asia from that of Australasia.
What type of plate boundary exists between the Antarctic and South American plates?
The easterly edge is a divergent boundary with the African Plate; the southerly edge is a complex boundary with the Antarctic Plate, the Scotia Plate, and the Sandwich Plate; the westerly edge is a convergent boundary with the subducting Nazca Plate; and the northerly edge is a boundary with the Caribbean Plate and the …
Is the Antarctic Plate convergent or divergent?
Today, about 95\% of the Antarctic plate is surrounded by divergent plate boundaries: the Southwest Indian Ridge, the Southeast Indian Ridge, and the American-Antarctica Ridge.
What type of plate boundary caused the Andes Mountains to form?
It is the result of a convergent plate boundary between the Nazca Plate and the South American Plate. 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.
Is the Andes oceanic or continental?
Oceanic/Continental: The Andes. The Nazca Plate is moving eastwards, towards the South American Plate, at about 79mm per year. Where the two plates meet, the denser oceanic lithosphere of the Nazca Plate is forced down and under the more buoyant continental lithosphere of the South American Plate, descending at an angle into…
Why are there so many volcanoes in the Andes Mountains?
The Andes range has many active volcanoes distributed in four volcanic zones separated by areas of inactivity. The Andean volcanism is a result of subduction of the Nazca Plate and Antarctic Plate underneath the South American Plate.
What type of lithosphere are the Andes and the Nazca Plate?
Oceanic/Continental: The Andes. Where the two plates meet, the denser oceanic lithosphere of the Nazca Plate is forced down and under the more buoyant continental lithosphere of the South American Plate, descending at an angle into the mantle in a process called subduction. This is marked on the ocean surface by the presence of the Peru-Chile…
