What kind of plate boundary runs through Chile and the Tonga trench?
The eastern margin is a convergent boundary subduction zone under the South American Plate and the Andes Mountains, forming the Peru–Chile Trench.
What is the plate boundary of trenches?
In particular, ocean trenches are a feature of convergent plate boundaries, where two or more tectonic plates meet. At many convergent plate boundaries, dense lithosphere melts or slides beneath less-dense lithosphere in a process called subduction, creating a trench.
Where does subduction occur?
convergent plate boundaries
Subduction zones are where the cold oceanic lithosphere sinks back into the mantle and is recycled. They are found at convergent plate boundaries, where the oceanic lithosphere of one plate converges with the less dense lithosphere of another plate.
What plates formed the Mariana Trench?
The boundary between the Mariana and the Pacific Plate to the east is a subduction zone with the Pacific Plate subducting beneath the Mariana. This eastern subduction is divided into the Mariana Trench, which forms the southeastern boundary, and the Izu–Ogasawara Trench the northeastern boundary.
Is Chile on a convergent plate boundary?
Earthquakes and volcanic activity are also common at another type of boundary: convergent boundaries. Chile is a South American country that lies along a convergent plate boundary. Convergent boundaries are found where two plates move toward each other. As the plates collide, one plate goes underneath the other.
Is Chile on a convergent or divergent boundary?
Earthquakes and volcanic activity are also common at another type of boundary: convergent boundaries. Chile is a South American country that lies along a convergent plate boundary. Convergent boundaries are found where two plates move toward each other.
What type of plate boundary was the Chile earthquake 2010?
convergent plate boundary
This has been interpreted as suggesting a link between upper plate (South American plate) structure and rupture length. Chile has been at a convergent plate boundary that generates megathrust earthquakes since the Paleozoic era (500 million years ago).
What plate boundary is Chile?
Chile is located along the convergent boundary between the Nazca Plate and the South American Plate, so it experiences a lot of earthquakes and volcanic activity.
Is Chile on a divergent plate boundary?
Chile, and the other countries of South America, lie on top of the South American tectonic plate. To the west of Chile, the Nazca Plate extends beneath the Pacific Ocean and meets the Pacific Plate along a divergent plate boundary called the East Pacific Rise.
What are examples of divergent boundaries?
Examples
- Mid-Atlantic Ridge.
- Red Sea Rift.
- Baikal Rift Zone.
- East African Rift.
- East Pacific Rise.
- Gakkel Ridge.
- Galapagos Rise.
- Explorer Ridge.
What does a convergent boundary form?
Convergent boundaries can form mountains, volcanos, or subduction zones that form large trenches. When two plates collide, the crusts can push together to form mountain ranges. This is how the Himalayan mountains were formed. Convergent boundaries between oceanic and continental boundaries feature a subduction zone.
What type of boundary is Chile on?
To the west of Chile, the Nazca Plate extends beneath the Pacific Ocean and meets the Pacific Plate along a divergent plate boundary called the East Pacific Rise. The southern edge of the Nazca plate adjoins the Antarctic Plate along another divergent plate boundary called the Chile Rise.
Is Chile on a convergent boundary?
What are examples of convergent boundaries?
Examples of continent-continent convergent boundaries are the collision of the India Plate with the Eurasian Plate, creating the Himalaya Mountains, and the collision of the African Plate with the Eurasian Plate, creating the series of ranges extending from the Alps in Europe to the Zagros Mountains in Iran.
