No. While only oceanic crust can subduct it is not always subducting. When two oceanic plates converge, only one of them subducts.

When an oceanic plate digs into earths hot interior what occurs?
When an oceanic plate subducts below another continental or oceanic plate, the cold, wet, dense rock and sediments slowly dive into the asthenosphere, where, due to the volume of water contained in the subducting plate, the melting point of the subducting plate is lower than the surrounding rock. Volcanoes may result from the rising of molten material created by the subduction.
What is subducting ocean plate?
An ocean plate is subducting if it is flowing under a less dense plate at a convergent plate boundary.
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.
Which is an example of a terrane?
oceanic crust and continental crust collide, with the continental crust subducting under the oceanic
Is the Pacific plate and oceanic plate or continental plate?
It is oceanic
What are island arches?
A series of volcanic islands formed by an older oceanic plate subducting under a newer oceanic plate.
What happends when an oceanic plate goes under a continental plate?
When an oceanic plate goes under a continental plate, the subducting plate ---> oceanic creates a curved line of volcanoes along the edge of the overlying continental plate.
What kind of plate boundary has the most explosive volcanoes?
Convergent with the oceanic plate subducting under the continental plate.

Was Mount Tambora formed by a convergent plate boundary or a divergent plate boundary?
It was formed from the volcanism created by a subducting oceanic plate at a convergent plate boundary.
How do the mountains that form along an oceanic-oceanic convergent boundary differ from those associated with an oceanic-continental convergent boundary?
In a oceanic-continentalconvergent boundaryyou normally get subduction , when one plate slides under another. In this case the plate subducting, or going under is the oceanic plate ( it is more dense ), so the mountains would be just of the continental plate. In aoceanic-oceanic convergent boundary the mountains would just be oceanic ( basalt).
Where were the older rocks on the sea floor found?
The oldest layers of sea floor would exist at the bottom of the Marianas Trench, where oceanic plate subduction is occurring. The subducting oceanic plate is less than 200 million years in age.
What is subducting ocean plate?
An ocean plate is subducting if it is flowing under a less dense plate at a convergent plate boundary.
Which tectonic plates cause the Andes mountains to rise?
The Andes Mountain Range is a result of the Nazca Plate subducting under the South American Plate.
What are oceanic-oceanic and oceanic-continental subduction boundaries?
In the scope of lithospheric plate movements, both boundaries are areas where the more dense of the colliding plates slides under the lighter one, and moves toward the mantle. The melting of the subducted crust as it nears the mantle may cause volcanism either on the sea floor or on the continental land mass. Earthquakes will also result as the subducting rocks break and grind their way past the non-subducting plate rock.
Which plate is subducting beneath South American plate?
Nazca
