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 ^ ^
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.
Volcanoes are most commonly associated with the top plate in subduction zones.
Subduction zones have the deepest earthquakes.
Oceanic plates are pushed down into the upper mantle in a process known as subduction. This occurs at convergent plate boundaries where one tectonic plate is forced beneath another due to differences in density. Subduction zones are associated with earthquakes and volcanic activity.
Subduction zones are formed when one tectonic plate is forced beneath another plate. This process occurs due to the differences in density between the plates, with the denser plate sinking below the less dense plate. The development of subduction zones is primarily driven by the movement of tectonic plates and the forces associated with plate boundaries. The convergence of plates, where one plate is pushed beneath another, is a key process that contributes to the formation of subduction zones. Additionally, the presence of oceanic crust, which is denser than continental crust, can also play a role in the development of subduction zones.
Trenches are deep ocean features of subduction zones.
Mid-ocean ridges are not associated with subduction zones. They are divergent plate boundaries where tectonic plates are moving away from each other, leading to the formation of new oceanic crust. Subduction zones, on the other hand, are convergent plate boundaries where one tectonic plate is being forced beneath another.

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

Convergent oceanic - continental and oceanic - oceanic boundaries.
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 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.
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.
Explosive volcanoes are most common at subduction zones.
This is not an assignment we can do. You have to do it .
