When two oceanic plates or two plates both containing oceanic crust collide or converge, the convergent boundary will form a trench. The plate which has the higher density will plunge beneath the other plate forming a trench.

What is the plate with oceanic crust sinking under one another plate with oceanic crust?

When one plate sinks under the other, it is callled subduction, no matter what kind of plate it is. When two oceanic plates collide, they form trenches(i.e. the mariana trench). Hope this answers your question!!!


Where is the oceanic crust sinking into mantle?

Usually when it meets another tectonic plate at a convergent plate boundary. If the oceanic plate converges with a continental plate the denser oceanic plate will be forced under the continental plate. If it converges with another oceanic plate the older (and therefore cooler and denser) plate will be forced under the younger plate.

What does sub-duction mean?

Oceanic subduction is a plate with oceanic crust sinking under another plate with oceanic crust.


Is oceanic crust slide under oceanic crust during subduction?

Yes, oceanic crust can slide under oceanic crust during subduction at convergent plate boundaries. This process occurs when a more dense oceanic plate descends beneath another oceanic plate, leading to the formation of a subduction zone.


What happens to the oceanic crust that is pushed down at the trench?

When oceanic crust is pushed down at a trench, it undergoes a process called subduction. This involves the denser oceanic plate sinking beneath a lighter continental or another oceanic plate, leading to the formation of deep oceanic trenches. As the crust descends, it can cause geological phenomena such as earthquakes and volcanic activity, as the subducting plate melts and interacts with the mantle. Eventually, the material may contribute to the formation of magma, which can lead to volcanic eruptions above the subduction zone.


What happens when an oceanic plate collides with a continental plate?

when oceanic crust and continental crust collide, the oceanic crust sinks down beneath the continental crust. this is called subduction.


What is a characteristic of subduction?

The correct answers are - B. Where oceanic crust meets continental crust, and C. Earthquakes.Subduction zones appear only on places where a crust of lower density (oceanic crust) meets a crust of higher density (continental crust).On the places where the oceanic crust meets the continental crust, the oceanic crust goes beneath the continental crust, this makes changes and readjustments in the inner part of the crust, and plus there's significant pressure from the mantle layer from beneath, so earthquakes are a very common occurrence.Check all that apply. A. Broad river deltas B. Where oceanic crust meets continental crust C. Earthquakes D. Two continents collide


Description of oceanic-oceanic subduction?

Occurs when ocean crust sinks under continental crust, it sinks because it's colder and denser,at these sites, deep-ocean trenches also form along with coastal mountains. As the oceanic crust moves, these trenches often causes underwater earthquake, as the crust sinks under a continent, the crust buckles to form a range of mountains, like island arcs, parallel to a deep-ocean trench. Some of the mountains are volcanoes, which form as melted oceaninc crust rises through the top plate. For example: Cascade Mountains in Oregon and Washington.


What happens when a plate of oceanic crust collides with a plate of oceanic crust?

The oceanic plate is made of denser (and thinner) rock than the continental crust, so the oceanic plate gets subducted (pushed underneath) where it descends and gets melted by geothermal heat.


What happens when a plate of oceanic crust collides with a plate of Continetal crust why?

the oceanic crust slides down and burns in the mantle and forms a volcano
