An oceanic plate subducts into the mantle at convergent plate boundaries.
When an oceanic plate converges with a continental plate, the oceanic plate slips under the continental one and into the mantle in a process called subduction. The area will be prone to large earthquakes and tsunamis. A chain of volcanoes will form on the continent.
A subduction zone at a convergent plate boundary. Undersea trenches are formed where the oceanic plate subducts, and volcanism and earthquakes may result from the partial melting and downward movement of the subducting crust.
Convergent plates are two tectonic plates that are colliding as they move toward each other. There are several types of converging plate boundaries.Oceanic to oceanic plate convergence:Where an oceanic plate collides with another oceanic plate, the more dense plate sub ducts into the mantle. The subduction results in the partial melting of lithospheric rocks above the area of the subduction, causing underwater volcanoes to form. If the volcanoes grow to reach the surface, volcanic arc islands are formed.Oceanic to continental plate convergence:Where an oceanic plate collides with a continental plate, the oceanic plate is subducted due to the fact that it is more dense, which can also cause volcanism and mountain building.Continental to continental plate convergence:Where two continental plates collide, neither subducts into the mantle, the crust is thickened, and mountain ranges are formed from the thickening and uplift.

When two plates move towards one another, they form either a subduction zone or a continental collision. This depends on the nature of the plates involved. In a subduction zone, the subducting plate, which is normally a plate with oceanic crust, moves beneath the other plate, which can be made of either oceanic or continental crust. During collisions between two continental plates, large mountain ranges, such as the Himalayas are formed. Oceanic crust is a type of crust that is submerged in huge bodies of water, while continental crust is the type of crust beneath the continents. Oceanic crust is thinner but denser, while the continental crust is thicker but lighter. Whenever a continental crust and an oceanic crust meets and collides, they form a convergence zone. The oceanic crust sinks below the continental crust(subduction zone) because it is denser. As it sinks into the mantle, it becomes magma which soon rises up to the surface to stabilize the mantle, thus creating a volcano. The continental crust, being the lighter one, does not sink. It may fold and form mountains. The nature of a convergent boundary depends on the type of lithosphere in the plates that are colliding. Where a dense oceanic plate collides with a less-dense continental plate, the oceanic plate is typically thrust underneath because of the greater buoyancy of the continental lithosphere, forming a subduction zone. At the surface, the topographic expression is commonly an oceanic trench on the ocean side and a mountain range on the continental side. An example of a continental-oceanic subduction zone is the area along the western coast of South America where the oceanic Nazca Plate is being subducted beneath the continental South American Plate.
subduction zone
This is known as a subduction zone.
When an oceanic plate converges with a continental plate, the oceanic plate slips under the continental one and into the mantle in a process called subduction. The area will be prone to large earthquakes and tsunamis. A chain of volcanoes will form on the continent.
The Nazca Plate and the South American Plate are colliding. Because oceanic plates like the Nazca are more dense than continental plates, they are forced below the continental plate and subduct, or flow downward into the mantle at varying degrees of descent from the area of collision!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Not usually, as the rock they are made of (mostly granite) is too light to sink into the mantle (mostly denser basalt). Small fragments of continental crust can get entrained in a subducting oceanic plate and be dragged down into the mantle as that plate subducts. Where continental crust collides with oceanic crust, it always floats forcing the oceanic crust down and causing it to subduct. Where continental crust collides with continental crust, both plates crumple and compress dramatically, being forced upward into unusually high mountains (e.g. the Himalayas) and downward into deep continental roots that support the weight of those mountains. Nothing subducts in this case. But whole continental plates subducting does not happen, while much more oceanic plate area has been subducted in the history of the earth than the total surface area of the earth.
if the western side of the plate is in the midoceanic ridge side then the other side ie. the eastern side of the plate would subduct under another plate on that side..as u know that earth's area is constant and no extra mass can be added so if one part is enlarging then the other part should obviously subduct...note thta' the eastern margin has the oldest rock...oldest rocks have high density so it will subduct under another younger oceanic plate or continental plate..
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.
