What would happen if the continental crust and the oceanic crust went into each other?

In a convergent plate collision between continental and oceanic plates, the more dense oceanic plate would subduct, or move underneath, the less dense continental plate, eventually melting into the mantle at the leading edge.

What happens at a destructive margin?
A destructive margin is when the oceanic crust moves towards the continental crust and slip under it (oceanic crust is heavier than the continental crust). This can build up a lot of pressure between the plates.
Why does the oceanic crust go under the continental crust when they collide?
because the ocean base is hevier than the other crust
What is the difference between the oceanic crust and continental crust and how does this influence plate boundary interactions?
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.
What is continental volcanic arc?
I think its a chain of volcanoes form when oceanic crustsubducts beneath other oceanic crust on an adjacent plate. . (:
Where is old seafloor destroyed?
Oceanic crust isn't destroyed because it's old; it is, in fact, destroyed due to destructive plate boundaries. This is where a continental plate and an oceanic plate move towards each other. As the oceanic crust is denser, it is pushed under the continental plate. Here it is forced into the mantle of the earth, where it is destroyed due to heat and convection currents.
What is the other type of crust the continental crust and what?
Oceanic Crust
What are convertgent boundaries?
A conversion boundary is a place where 2 tectonic plates are mving toward each other. There are 3 types of convergent boundaries OCEANIC CRUST-OCEANIC CRUST OCEANIC CRUST-CONTINENTAL CRUST CONTINENTAL CRUST-CONTINENTAL CRUST They are classified according to their crust
Why does the oceanic sink beneath continental crust at convergent boundaries?
The continental crust is less dense than the oceanic crust. That's the reason we find that the oceanic crust sinks (subducts) beneath the continental crust.Continental crust is less dense than oceanic crust and so cannot sink below it.
Differences between oceanic-oceanic and oceanic-continental subduction boundary?
Oceanic to oceanic- one plate sinks under the other Oceanic- Continental ocean crust sinks under the other
Is the crust formed or destroyed at the sliding boundary?
At convergent boundaries are boundaries the crust is destroyed by subduction of oceanic crust underneath continental crust or other oceanic crust.
Is the crust formed or destroyed at a sliding boundary?
At convergent boundaries are boundaries the crust is destroyed by subduction of oceanic crust underneath continental crust or other oceanic crust.
Which type of crust will rise on top of the other?
Continental crust over Oceanic crust.

How big is the indo-australian plate?
No, it is not an oceanic plate. It is a continental plate but with oceanic crust. Crust is different from plate. A plate is made up of many crust. The crust under the ocean is oceanic crust, while the crust where continent is found is called continental crust. Most of the plates are made up off both continental and oceanic crust. If a plate has continental crusts, then it is a continental plate. Only if a plate is all made up of oceanic crusts, meaning that there is no land on it, then the plate is called oceanic plate. In the world, the major oceanic plates include Pacific Plate, Nazca Plate, Cocos Plate and Philippines Plate. Other are all continental plate.
Why does the oceanic crust go under the continental crust when they collide?
because the ocean base is hevier than the other crust
Is the theory of the continental drift true?
Continental Drift is an obsolete name for the theory of Plate Tectonics and yes, it is true. It has been proved in many ways, by comparing the composition of oceanic crust and its ages with that of the continental crust, by plotting the reversals of magnetism in the oceanic crust and many other ways.
