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.
What else can I help you with?
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.
Where is oceanic crust pulled down into the mantle?
Oceanic crust is pulled down into the mantle at subduction zones, where one tectonic plate is forced underneath another plate. This process is a key component of plate tectonics and is responsible for the recycling of Earth's crust.
What forms where an oceanic plate begins to move down in a subduction zone?
When an oceanic plate begins to move down in a subduction zone, it forms a deep ocean trench at the boundary where the plates meet. As the oceanic plate descends into the mantle, it creates a subduction zone where intense geological activity like earthquakes and volcanic eruptions can occur. This process is a fundamental mechanism in plate tectonics, driving the movement of Earth's lithosphere.
How does subduction occur?
A plate will subduct for tens to hundreds of millions of years.
What does oceanic plates mean?
Oceanic plates are sections of the Earth's lithosphere that form the bedrock beneath the world's oceans. These plates are typically denser and younger than continental plates, and they are constantly moving due to the process of plate tectonics. Subduction zones are often found at the boundaries where oceanic plates meet continental plates.
What happens when oceanic and continental crust meets?
When oceanic and continental crust meet, a subduction zone is formed where the denser oceanic crust is forced beneath the less dense continental crust. This process typically results in the formation of deep ocean trenches, volcanic arcs, and earthquakes.
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.
Where do subduction boundarys occur?
Subduction boundaries occur where one tectonic plate sinks below another, typically in oceanic-continental or oceanic-oceanic plate interactions. These boundaries are associated with deep ocean trenches, volcanic arcs, and earthquakes due to the collision and subduction of the plates. Examples include the boundary between the Pacific Plate and the North American Plate along the west coast of South America.
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.
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.
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.
Where is oceanic crust pulled down into the mantle?
Oceanic crust is pulled down into the mantle at subduction zones, where one tectonic plate is forced underneath another plate. This process is a key component of plate tectonics and is responsible for the recycling of Earth's crust.
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.
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.

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?
Subduction takes place at a convergent plate boundary, where two tectonic plates collide and one plate is forced beneath the other into the Earth's mantle. This process is associated with the formation of deep ocean trenches and volcanic arcs.
