What deep ocean feature form at subduction zones?

Trenches are deep ocean features of subduction zones.


What deep feature of the ocean floor is found at subduction zones?

A trench.


Which geographic feature is associated with subduction zones?

Subduction Zones are usually known to be part of the Destructive Plate Boundary. The changes that occur in this boundary are: Oceanic crust moves towards the continental crust, but due to the weight of the oceanic crust, the oceanic crust sinks and gets destroyed. This forms deep sea trenches and island archs with volcanoes. As the oceanic crust is forced downwards, the increase in pressure can trigger earthquakes to strike... Basically, the two plates (oceanic and continental) are associated with subduction zones.... Hope this helped ^ ^


Which metamorphic facies is associated with subduction zones?

blue schist facies


What geological feature does subduction zones cause?

Subductions zones result in the formation of a trench and also volcanoes on the overriding plate


Would the most violent earth quacks be associated with spreading centers or subduction zones?

The most violent earthquakes are generally associated with subduction zones where tectonic plates collide and one is forced beneath the other. These subduction zones can produce very large and destructive earthquakes, such as the 2004 Indian Ocean earthquake and tsunami. Spreading centers, on the other hand, usually produce smaller earthquakes due to the gradual separation of tectonic plates.


What type of boundaries are subduction zones associated with?

Convergent oceanic - continental and oceanic - oceanic boundaries.


Is Shield volcanoes found along subduction zones?

Cone volcanoes which are likely to erupt explosively are found at subduction zones. Spreading zones (constructive plate boundaries) and hot spots produce quieter volcanoes because their lava is thinner. The ones at hot spots are shield volcanoes.


The blank ocean basin is rimmed by the most subduction zones?

The Pacific Ocean basin is rimmed by the most subduction zones. These subduction zones form as one tectonic plate is forced beneath another, creating deep ocean trenches. The Pacific Ring of Fire, which encircles the Pacific Ocean, is known for having numerous subduction zones and is associated with high levels of seismic activity and volcanic eruptions.


What is the region where oceanic lithosphere sinks into the asthenosphere?

This process occurs at subduction zones, where one tectonic plate descends beneath another plate into the asthenosphere. Subduction zones are typically associated with deep ocean trenches and volcanic arcs.


Where are the most explosive volcanoes subduction zones or rift zones?

Explosive volcanoes are most common at subduction zones.


Is the Korean peninsula considered to be an active tectonic or volcanic region?

There are active volcanoes in Korea with associated plate subduction zones.
