the oceanic plate is less bouyant so it slides under the continental plate

Why is oceanic lithosphere subducted while continental lithosphere is not?
The density of the continental (granitic) lithosphere is lower than oceanic (basaltic) lithosphere. Consequently, due to buoyancy, the continental crust rides above the oceanic lithosphere and thus is not subducted. However, it is thought that pieces of the continental lithosphere break off and are subducted along with the oceanic lithosphere.
Where slab of oceanic lithosphere are subducted under continental lithosphere?
destuctive plate margin
What happens when continental and oceanic lithospheres collide?
When oceanic lithosphere and continental lithosphere collide, the continental lithosphere may be obducted over the oceanic lithosphere or the oceanic lithosphere may be subducted under the continental lithosphere. The latter is thought to be more common. This subduction and obduction generally results in tectonic activity such as volcanoes and earthquakes.
Is oceanic lithosphere lighter than continental lithosphere?
no
Why oceanic crust is always subducted underneath continental crust?
Due to the higher density of the oceanic crust it is subducted underneath the continental crust.

When an oceanic plate collides with a continental plate which plate is subducted?
When an oceanic plate and a continental plate collide, the oceanic plate is always subducted. Oceanic plates are denser than continental plates, and they have a higher iron content. Since they are denser, oceanic plates always sink below the continental plate in the event of a collision.
Which continental margin occur where oceanic lithosphere is being subducted beneath the edge of a continent?
active continential margins
Is oceanic lithosphere lighter than continental lithosphere?
no
Why does oceanic lithosphere sink beneath convergent lithosphere at convergent boundaries?
As odd as it is to think of things this way, continental lithosphere is more buoyant than oceanic lithosphere. The oceanic lithosphere is more dense.
Name the two types of lithospheric plates?
There are two types of lithosphere: the oceanic lithosphere and the continental lithosphere. The oceanic lithosphere exists in the ocean basins while the continental lithosphere exists in the continental crust.
Why oceanic crust is always subducted underneath continental crust?
Due to the higher density of the oceanic crust it is subducted underneath the continental crust.
Why does oceanic lithosphere sub duct while continental lithosphere does not?
Oceanic lithosphere is dense enough to be forced down into the mantle. Continental lithosphere is not.
What two layers make up the lithospere?
The two layers of the lithosphere is made up of the oceanic lithosphere and continental lithosphere. The oceanic lithosphere is associated with oceanic crust and the ocean basins. The continental lithosphere is associated with the continental crust.
What forms from collision of continental crust and oceanic crust?
A basic mountain should be formed from the collision of continental crust and oceanic crustAnswerWhen an oceanic and a continental crust collide, the heavier oceanic crust tends to subduct under the lighter continental crust. Because of the collision and corresponding compression and also because of volcanism related to dehydration and melting of the subducted plate a mountain range is formed. The Andes mountain range is a, if not the, most typical example.
