The continental plate pushed on the right side of South America is the Nazca Plate. This tectonic plate is subducting beneath the South American Plate, which leads to significant geological activity, including the formation of the Andes Mountains and frequent earthquakes in the region. The interaction between these two plates is a key factor in the tectonics of South America.

What convergent boundary is found along the west coast of south America?
On the west coast of South America the denser ballistic ocean crust of the pacific plate is pushed under the lighter granite continental crust of South America. This causes a subduction zone.By Donovan Lopez
Does the south American tectonic plate only have continental crust?
No, the South American tectonic plate comprises both oceanic and continental crust. It is the Earth's largest continental plate, covering much of South America and part of the Atlantic Ocean.
What kind of plate is the South American plate?
The South American plate is a major tectonic plate that covers most of the continent of South America. It is primarily composed of continental crust.
What are some examples of collisions between a continental plate and an oceanic plate?
Examples of collisions between a continental plate and an oceanic plate include the Andes Mountains in South America, where the Nazca Plate is subducting beneath the South American Plate, and the Himalayas in Asia, where the Indian Plate is colliding with the Eurasian Plate. These collisions result in the formation of mountain ranges and can lead to intense seismic activity and volcanic eruptions.
Is the andes a continental-continental?
Yes, the Andes is a convergent boundary where the South American Plate and the Nazca Plate collide. This collision creates extensive mountain ranges along the western coast of South America.
How were the Andes in South America formed?
The Andes are formed by the collision of the Nazca Plate (oceanic) and the South American Plate (continental). The collision causes the continental crust to buckle and form fold mountains which are then peppered with volcanoes caused by melting of the Nazca plate as it is forced down into the Earth's mantle.
What is an example of oceanic-continental convergence?
Andes, convergence between South American Plate and Pacific Plate
What boundary is formed when and oceanic plate is pushed under a continental plate?
A subduction zone is formed when an oceanic plate is pushed under a continental plate. This process can lead to the formation of deep ocean trenches, volcanic arcs, and seismic activity.
Convergent continental oceanic definition?
Convergent continental-oceanic boundaries are locations where a continental plate collides with an oceanic plate, resulting in subduction of the denser oceanic plate beneath the less dense continental plate. This collision can lead to the formation of deep oceanic trenches, volcanic arcs, and earthquakes. The Andes Mountains in South America and the Cascades in North America are examples of convergent continental-oceanic boundaries.
What is the continent of The Falkland Islands?
South America. About 400 miles of the coast of Argentina, however it is a dependency of the United Kingdom although Argentina disputes ownership. In continental plate terms, it is on the South American plate, but lies close to the boundary with the Scotia plate to the south
Where are continental volcanic arcs found?
Continental volcanic arcs are found at the boundaries where an oceanic plate subducts beneath a continental plate. Examples include the Andes in South America, the Cascades in North America, and the Japan Alps in Japan. These volcanic arcs are associated with explosive eruptions due to the interaction between the subducting oceanic plate and the overlying continental plate.
When an oceanic plate is pushed under a continental plate resulting in volcanic activity this type of boundary forms?
A subduction zone is formed when an oceanic plate is pushed under a continental plate, resulting in volcanic activity. Oceanic crust is denser and sinks beneath the less dense continental crust, leading to the formation of volcanic arcs on the overriding plate.
