What type of plate boundary is directly west and adjacent to the plate on which Ecuador is located?
Nazca plate
What is the tectonic setting of volcanism in Ecuador?
The volcanoes of Ecuador belong to the Northern Volcanic Zone of the Andes, which is the result of subduction of the Nazca Pacific oceanic plate under the continental plate of South America. In Ecuador, the volcanoes occur on 4 chains. All active (and a few extinct) volcanoes of Ecuador are listed.
What is the most common boundary?
The most common divergent boundaries are the mid-ocean ridges that launched the plate tectonics revolution, and the Mid-Atlantic Ridge is a classic example (see Figure 3). Shallow earthquakes and minor basaltic lava flows characterize divergent boundaries at mid-ocean ridges.
Where can a convergent boundary be found?
In the ocean basins, convergent plate margins are marked by deep trenches in the sea floor. The convergent plate boundaries that occur on continents are the collisional mountain belts. Following are 3 examples of different tectonic settings of convergent plate boundaries.
What are the three types of convergent boundaries?
There are three types of convergent plate boundaries: oceanic-oceanic boundaries, oceanic-continental boundaries, and continental-continental boundaries.
Why do Convergent boundaries occur?
Convergent (Colliding): This occurs when plates move towards each other and collide. When a continental plate meets an oceanic plate, the thinner, denser, and more flexible oceanic plate sinks beneath the thicker, more rigid continental plate.
How are convergent boundaries formed?
Convergent boundaries are boundaries where two plates are pushing into each other. They are formed when two plates collide, either crumpling up and forming mountains or pushing one of the plates under the other and back into the mantle to melt.
What are the effects of a convergent boundary?
Effects found at a convergent boundary between continental plates include: intense folding and faulting, a broad folded mountain range, shallow earthquake activity, shortening and thickening of the plates within the collision zone.
What are the similarities between convergent and divergent boundaries?
The similarities are that a boundary of any kind marks the line between two tectonic plates. Similarities between divergent and convergent boundaries include magma or lava flows, formation of new topographic features and re-shaping of landmasses.
What is an example of a transform boundary?
The most famous example of this is the San Andreas Fault Zone of western North America. The San Andreas connects a divergent boundary in the Gulf of California with the Cascadia subduction zone. Another example of a transform boundary on land is the Alpine Fault of New Zealand.
At what type of boundary would you observe subduction?
convergent plate boundaries
