along a divergent plate boundary

divergent plate boundary
A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface solidifying to create new oceanic crust. The Mid-Atlantic Ridge is an example of divergent plate boundaries.

What type of plate boundary caused the Chile earthquake 2010?

Chile Earthuake 27 Febraruy 2010. The earthquake occurred on the boundary between the South American and Nazca tectonic plates that runs down the west coast of Chile and has also resulted in the formation of the Andes.

What type of plate boundary is the South American Plate?

divergent plate boundary
The South American Plate is the smallest major plate But the eastern edge lies in the Atlantic Ocean at a divergent plate boundary. Along the African Plate boundary these two plate boundaries pull apart from each other. This diverging plate motion creates some of the youngest oceanic crust on the planet.Jan 5 2021

Are tectonic plates?

Tectonic plates are pieces of Earth’s crust and uppermost mantle together referred to as the lithosphere. The plates are around 100 km (62 mi) thick and consist of two principal types of material: oceanic crust (also called sima from silicon and magnesium) and continental crust (sial from silicon and aluminium).

What type of convergent boundary is the Peru Chile trench?

boundary subduction zone
The eastern margin of the Nazca Plate is a convergent boundary subduction zone under the South American Plate and the Andes Mountains forming the Peru–Chile Trench. Two seamount ridges within the Nazca Plate enter the subduction zone along this trench: the Nazca Ridge and the Juan Fernández Ridge.

Is the Nazca Plate convergent or divergent?

The Nazca plate is an oceanic tectonic plate in the southeastern Pacific Ocean that shares both convergent and divergent boundaries corners multiple triple junctions contains three seamount chains overrides four hotspots and is responsible for the creation of the Andean orogeny (Figure 1).

What type of boundary is between Nazca and South America?

According to the given figures convergent oceanic-oceanic plate boundary takes place between the South American Plate and the Nazca Plate. The Peru–Chile Trench outlines the boundary between the subducting Nazca Plate and the overriding South American Plate. The trench was created thanks to a convergent boundary.

Is the Caribbean plate oceanic or continental?

The Caribbean Plate is a mostly oceanic tectonic plate underlying Central America and the Caribbean Sea off the north coast of South America.

How did the Chile Rise form?

The age of the subducting crust becomes progressively younger from north to south along the eastern edge of the Nazca plate until the newly-formed crust at the actively spreading Chile Rise enters the trench. … The Chile Rise continues to spread as it is thrust beneath the continental margin of South America.

What type of plate boundary exists in South America and Antarctic Plate?

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 …

What type of plate boundary is the East Pacific Ridge?

The East Pacific Rise is a “divergent” plate boundary where huge slabs of the Earth’s crust (plates) are moving away from each other.

What two plates are converging near Chile that caused the earthquake?

Chile is largely located on the boarders of the oceanic Nazca plate and the continental South American plate. The difference in motion between these two plates is the driving mechanism behind earthquakes happening in this region. The two plates are converging at roughly 7 to 10 meters per century.

Was the Valdivia earthquake a strike slip fault?

Detailed analyses of historical seismograms indicate that the 1960 Valdivia Chilean earthquake had a large strike-slip component in addition to the comparable-size well-known thrust component.

Is Valdivia on a plate boundary?

It marks the plate boundary between the subducting Nazca plate and the South America plate where the oceanic crust and lithosphere of the Nazca plate begin their descent into the mantle beneath South America.

What type of tectonic plate boundary is located at mid ocean ridges?

divergent plate boundaries
Mid-ocean ridges occur along divergent plate boundaries where new ocean floor is created as the Earth’s tectonic plates spread apart. As the plates separate molten rock rises to the seafloor producing enormous volcanic eruptions of basalt.

What are the different types of plate boundaries?

There are three main types of plate boundaries:
  • Convergent boundaries: where two plates are colliding. Subduction zones occur when one or both of the tectonic plates are composed of oceanic crust. …
  • Divergent boundaries – where two plates are moving apart. …
  • Transform boundaries – where plates slide passed each other.

What type of plate boundary is the Alpine Fault?

transform boundary
In the middle the Alpine Fault is a transform boundary and has both dextral (right-lateral) strike-slip movement and uplift on the southeastern side. The uplift is due to an element of convergence between the plates meaning that the fault has a significant high-angle reverse oblique component to its displacement.

Is Chile on a fault line?

The Atacama Fault Zone (AFZ) is an extensive system of faults cutting across the Chilean Coastal Cordillera in Northern Chile between the Andean Mountain range and the Pacific Ocean. The fault system is North-South striking and runs for more than 1100 km North and up to 50 km in width through the Andean forearc region.

What plates caused the great Chilean earthquake?

The Chilean quake was spawned by a straightforward dip of the Nazca plate (ocean crust undergirding the Pacific Ocean off South America’s coast) as it slips eastward under the continent’s crust according to the USGS.

What is the plate boundary?

Plate boundaries are the edges where two plates meet. Most geologic activities including volcanoes earthquakes and mountain building take place at plate boundaries. … Convergent plate boundaries: the two plates move towards each other. Transform plate boundaries: the two plates slip past each other.

Is the South American Plate oceanic or continental?

two of these plates—the continental South American Plate and the oceanic Nazca Plate—gave rise to the orogenic (mountain-building) activity that produced the Andes.

What is the western boundary of the South American Plate?

Nazca plate
South American plate is bounded by African plate in the east Nazca plate in the west Antarctic plate and Scotia plate in the south and Caribbean plate and North American plate in the north.

Where are the tectonic plates?

In plate tectonics Earth’s outermost layer or lithosphere—made up of the crust and upper mantle—is broken into large rocky plates. These plates lie on top of a partially molten layer of rock called the asthenosphere.

Where are all the tectonic plates?

Earth’s thin outer shell is broken into big pieces called tectonic plates. These plates fit together like a puzzle but they’re not stuck in one place. They are floating on Earth’s mantle a really thick layer of hot flowing rock.

What type of plate is plate A?

Answer: Plate A is an oceanic plate because it is relatively thinner compared to plate B. While Plate B is a continental plate because it is thicker and floats higher than the other plate.
