How did the Nazca Plate form the Andes Mountain?
The Oceanic plate (Nazca Plate) is denser than the Continental plate (South American plate). Therefore, when the two plates collide, the Oceanic Plate is pushed downwards towards the mantle.This is known as "subduction". The conversion between these two plates create fold mountains and the fold mountains are pushed up over time above sea level and this creates the Andes Mountains.
How did the Nazca Plate form Volcanoes?
While pressure increases, at the same time, the heat produced by friction turns the descending crust into magma. The magma tries to escape and so it rises to the top and when it does this, a volcanic eruption occurs and that's how the plates created the 5 active volcanoes along the convergent boundary between the Nazca and the South American plates.
How did the Nazca Plate cause earthquakes?
The way earthquakes were caused were from plates and oceanic crust. Oceanic Crust moves towards another plate and because the oceanic crust is heavier, it is forced to move downwards and then pressure increases which causes the violent earthquakes to occur.
The Nazca moves eastward at a rate of 15-17 cm per year. It's activities include colliding with the South American plate, forming the Andes Mountains. This plate is moving away from the Pacific plate and the Cocos plate and is moving towards the South American plate and the Atlantic plate. It's subduction with the South American plate causes the earthquakes and volcanoes.
Two massive earthquakes have occurred on this plate. These earthquakes occurred due to the subduction of the Nazca and the South American plate. On May 22, 1960, was near Valdivia and its magnitude was an 9.5. On February 27, 2010, the earthquake in the Maule Region of Chile had a magnitude of 8.8. The largest earthquake ever recorded was in Bolivia on June 9, 1994. Its magnitude was 8.2. The epicenter was in a remote region of the Amazon Forest.
The Nazca Plate is home to the Galapagos Islands and this means that there are hot spots! One of the three major hot spots on this plate is the Galapagos hotspot. It is located at the Northern part of the plate. Another hot spot is the Juan Fernandez hotspot. It is located at the southern part of the plate. This plate and the Cocos plate pull apart at the divergent boundaries and formed the rift valley called the Galapagos Rift.
There are many earthquakes in this region. The earthquakes form along the borders of this plate. They occur there because of tectonics shifting and this is how different boundaries formed. At the edge, there are also volcanoes. The Nazca plate and the South American plate collided together at the convergent boundaries to form the Andes Mountains.
The Nazca plate collides with the South American plate and this forms a convergent boundary. At the border of the Pacific plate, a divergent boundary forms. At the border of the Cocos, the Nazca Plates, and the Antarctic plate, a transform boundary is formed.
The Nazca Plate is small and it is on the coast of South America. It is oceanic and located on the east of the Pacific Ocean.
The Nazca Plate is a tectonic plate in the eastern Pacific Ocean. It produced one of the largest earthquakes ever recorded by seismographs. It has 5 triple junctions, meaning that it is the point where the boundaries of three plate tectonics meet.
