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 is the name of the plate to the west and directly adjacent to the plate on which Chile is located?
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 tectonic plates is Ecuador on?
Ecuador sits on the edge
between the Nazca and South American tectonic plates
, the plates which make up the Earth surface.
What type of plate boundary is the South American Plate and Nazca Plate?
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.
What kind of plate boundary exists along the west coast of South America?
The west coast of South America is
a subduction zone
, which means that the oceanic plate, called the Nazca plate, is being forced beneath the adjacent continental plate. The Andes mountains were thrust upwards by this motion, and can still be considered “under construction” by the earth’s crust.
Why are earthquakes to be expected in Chile?
Chile is a hotspot for earthquakes because
the Nazca plate
, a tectonic plate which moves eastwards with a rate of 6.6 cm per year, collides with the South American plate off the Chilean coast. … Land was violently shifted up or down several meters, fundamentally changing the Chilean landscape.
How many tectonic plates are there?
how many tectonic plates are there? There are major, minor and micro tectonic plates. There are
seven major plates
: African, Antarctic, Eurasian, Indo-Australian, North American, Pacific and South American.
When was Ecuador’s last earthquake?

When was the last tsunami in Ecuador?
| Date Cause max. tidal wave | 03/11/2011 Earthquake in Japan (Honshu Island) with a magnitude of 9.1. The tsunami caused damages in 11 further countries. A total of 18,431 humans died. 6.1 m | 01/19/1958 Earthquake in Ecuador (Colombia-Ecuador) with a magnitude of 7.6. 0 m |

What plates caused the Ecuador Earthquake?
Ecuador is located in
the Nazca plate
which means that it have more probability of earthquakes. The reason for this is that the plates cannot simply glide past each other. Rather, stress builds up in both plates and when it exceeds the threshold of the rocks, the energy is released – causing earthquakes.
What type of plate boundary is between the Antarctic Plate and the Pacific Plate?
The southern side is
a divergent boundary
with the Antarctic Plate forming the Pacific–Antarctic Ridge.
Is the Nazca Plate convergent?
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).
Why is the Nazca Plate subducting?
The Nazca Plate is moving eastwards, towards the South American Plate, at about 79mm per year. The
friction between the plates prevents the subducting oceanic plate from sliding smoothly
. … As it descends, it drags against the overlying plate, causing both to fracture and deform.
What type of plate boundary is on the west coast?
San Andreas Transform Plate Boundary
The transform plate boundary between the Pacific and North American Plates in western California formed fairly recently. About 200 million years ago, a large tectonic plate (called the Farallon Plate) started to subduct beneath the western edge of North America.
How did the South American and African plates move?
How did the South American Plate and African Plate move? Earth’s plates move on top of a soft, solid layer of rock called the mantle. … The South American and African Plates moved
apart as a divergent boundary formed between them and an ocean basin formed and spread
.
What type of boundary is the west coast of America?
The west coast of is in fact
a plate boundary
that separates oceanic crust to the west from continental crust to the east.
