Which tectonic plates cause the Andes mountains to rise?
The Andes Mountain Range is a result of the Nazca Plate subducting under the South American Plate.
What happens when the nazca seafloor plate pushes into the so American continental plate?
When the Nazca seafloor plate pushes into the South American continental plate, it creates a convergent boundary. This leads to subduction, where the denser oceanic plate is forced beneath the less dense continental plate. This process can result in the formation of deep oceanic trenches, volcanic arcs, and seismic activity such as earthquakes.
What is an example of oceanic-continental convergence?
Andes, convergence between South American Plate and Pacific Plate
Name a plate that is entirely made of continental crust?
All major plates contain both continental and oceanic crust except for the Pacific and Nazca plates.
What is likely happening at the boundary between the Nazca plate and the South American plate?
Answer this question… Subduction of oceanic crust beneath continental crust
What has one continental plate and one oceanic plate?
A tectonic plate boundary where one continental plate and one oceanic plate meet is known as a convergent boundary. In this scenario, the denser oceanic plate typically subducts beneath the lighter continental plate, leading to geological phenomena such as the formation of mountain ranges, volcanic activity, and earthquakes. An example of this is the boundary between the Nazca Plate (oceanic) and the South American Plate (continental), which has resulted in the Andes mountain range and significant volcanic activity.
What are the three subtypes of convergent plate boundaries and give examples of types of landmass formed at each boundary?
The three subtypes of convergent plate boundaries are oceanic-continental, oceanic-oceanic, and continental-continental. At oceanic-continental boundaries, such as the Nazca Plate subducting beneath the South American Plate, volcanic mountain ranges like the Andes are formed. At oceanic-oceanic boundaries, like the Pacific Plate subducting beneath the North American Plate, island arcs such as the Aleutian Islands are created. Finally, at continental-continental boundaries, such as the collision of the Indian Plate with the Eurasian Plate, large mountain ranges like the Himalayas are formed.
Which one goes under oceanic - continental?
In the context of plate tectonics, the oceanic-continental boundary refers to the interaction between an oceanic plate and a continental plate. When these two plates converge, the denser oceanic plate typically subducts, or sinks, beneath the lighter continental plate. This process often leads to the formation of mountain ranges, deep ocean trenches, and volcanic activity along the continental edge. An example of this boundary is the subduction of the Nazca Plate beneath the South American Plate, resulting in the Andes mountain range.
What type of crust is found on the nazca plate?
It forms a convergent boundary with the South American Plate, divergent.
Are the Andes mountains a good example of oceanic - oceanic collision?
No, the Andes Mountains are not a result of oceanic-oceanic collision; they formed primarily due to the subduction of the Nazca Plate beneath the South American Plate, which is a continental plate. This process is classified as oceanic-continental convergence, where an oceanic plate is forced down into the mantle under a continental plate. The resulting geological activity created the Andes' complex structure, including volcanic activity and mountain formation. Oceanic-oceanic collisions typically lead to the creation of island arcs rather than continental mountain ranges like the Andes.
What type of crust can be found on the south American plat where it meets the nazca plate?
At the boundary where the South American Plate meets the Nazca Plate, you can find oceanic crust being subducted beneath continental crust. This subduction zone is characterized by the Nazca Plate, which is primarily composed of oceanic crust, descending into the mantle under the continental crust of the South American Plate. This interaction leads to significant geological activity, including the formation of the Andes mountain range and frequent earthquakes in the region.
