No subduction doesn't take place when two oceanic crust meet. When two oceanic crusts meet, it is called a divergent boundary. Crustal features vary such as one like mid-ocean rdges. Subducting takes place when an OCEANIC and CONTINENTAL plate meet not when two oceanic plates meet.

How does subduction occur?
A plate will subduct for tens to hundreds of millions of years.
What is it called when two tectonic plates colide?
It's referred to as a Convergent Boundary If 2 Continental Plates --> Mountains If 2 Oceanic Plates --> Subduction of Heavier (older) Plate If Continental-Oceanic --> Oceanic Plate slides under the Continental Plate (Subduction of Oceanic)
What is the result when continental plates meet oceanic plates?
If the plates are moving toward each other, the more dense oceanic plate will subduct underneath the less dense continental plate. Mountain ranges and volcanism may result as the water saturated subducting oceanic crust creates molten rock which attempts to rise to the surface.
Where is oceanic crust pulled down into the mantle?
It is pulled down along a fault line where two tectonic plates meet. If you are looking for a location there is a fault line right off the coast of california.
Why would there be a large number of natural disasters on the countrys where tectonic plates meet?
Tectonic plate movements are responsible for all earthquakes, and most volcanism and tsunami production on Earth. It's one of the hazards of living on a geologically active planet. Subduction zones, where the more dense plate dives under the lighter plate creates volcanism when the wet dense oceanic crust meets the hot plastic mantle.
Where do subduction boundarys occur?
There is no such thing as a subduction boundary, there are divergent, convergent, and transform boundaries. When there is a continental-oceanic convergent boundary (when a continental plate and an oceanic plate smash together) the oceanic plate, because it is more dense sinks into deeper layers of the earth. The area where the two plates meet makes a trench which is a subduction zone. The oceanic plate will melt into the earth and because of the excess lava it rises out onto the continent and makes a volcanic mountain and the lava erupts.
What happens at a subduction convergent boundary?
The oceanic crust (the denser crust) is subducted under the lighter crust which basically means that it goes under the upper crust as they meet so they don't crash into each other like at a collision zone.
What does sub-duction mean?
Oceanic subduction is a plate with oceanic crust sinking under another plate with oceanic crust.
How a subduction zone forms?
When two plates move together (at least one must be oceanic crust), one will sink beneath the other. The result is that a subduction zone forms between the two plates at the location where they meet.
What is the difference between the thickness of the continetal crust and oceanic crust?
In technical terms, the oceanic crust is denser than the continental crust so when the continental crust and the oceanic crust meet the continental crust will sink under and the oceanic crust will slide over and a volcano will be formed as well as producing earthquakes in the process.
Why does the oceanic crust move below continental crust?
The basaltic oceanic crust is more dense than the granitic continental crust. Therefore, when the two meet at plate margins, the oceanic crust usually subducts beneath the continental plate.
Convergent boundary with no subduction?
A convergent boundary with no subduction is a continental-continental boundary. Because oceanic crust is denser than continental crust, it is always the subducting plate in a oceanic-continental boundary. In an oceanic-oceanic boundary, one of the plates will subduct, depending on several factors. Continental plates are thicker and less dense than oceanic plates, and when they converge, they push up the area where the plates meet, forming mountain ranges (note that this is not the only, or even the predominant, method of mountain formation). The Himalayas are being formed as a result of a continental-continental boundary.
What kind of plate boundary does subduction take place at?
A convergent plate boundary. a piece of continental crust and a piece of oceanic crust meeting at a convergent boundary.
What is created by subduction?
In plate tectonics, a subduction zone forms where the boundaries of two plates that are being pushed into each other meet and one is forced down beneath the other one. The "forced down" plate is being subducted. The subduction zone is the area where one plate is shoved down and the other rides up over the top of the first one.

What happens when a oceanic and continental plate move towards each other?
It is called a destructive plate boundry...one type of crust is oceanic and the other is continental. when they meet the oceanic crust gets pushed down as it is heavier. the friction caused when it sinks creates huge earthquakes and the crust re-melts and gets forced upwards due to pressure to form a volcano.
Where does subduction happen?
subduction occurs where 2 continents meet or where the tectonic plates meet. :)
How does subduction occur?
A plate will subduct for tens to hundreds of millions of years.
