Continental crust is less dense and cooler than oceanic crust and less dense and cooler than the asthenosphere, therefore instead of subducting, it is pushed upward in a collision between continents, or floats over a subducting oceanic crust.

∙ 8y agoContinental crust is largely composed of silicate minerals which give it a lower density than oceanic crust, which contains more mafic minerals.
The mantle is even denser than oceanic crust, so that continental crust is far too buoyant to be subducted (except in special circumstances).
The continental crust cannot be subducted because the earth has no convergent boundaries, where subduction occurs.

Why is oceanic crust always subducted underneath the continental crust?
Oceanic crust subducts under continental crust because it is denser. Continental crust's density is too low for it to be forced into the mantle.
The process of an oceanic plate colliding with and descending underneath a continental plate?
The oceanic crust is subducted underneath the continental crust. This process is known as subduction.
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.
Which is an example of a terrane?
oceanic crust and continental crust collide, with the continental crust subducting under the oceanic
Differences of the continental crust and oceanic crust?
Thickness - continental = much thickerDensity - oceanic crust is denser than continental, which is why the oceanic crust subducts under the continental at destructive plates boundaries.
What do one oceanic and one continental crust produce when the oceanic crust is subducted under the continental one?
A trench and a strata volcano.
Why is oceanic crust always subducted underneath the continental crust?
Oceanic crust subducts under continental crust because it is denser. Continental crust's density is too low for it to be forced into the mantle.
Why is the oceanic plate subducted when an oceanic plate collides with a continental plate?
The Oceanic plate is subducted under the Continental plate because oceanic crust is much more dense than continental crust. The average density of the oceanic crust is 3g/cm^3 while the average density of continental crust is 2.7g/cm^3.
When does a plate carrying continental crust converges with a plate carrying oceanic crust?
The oceanic plates gets subducted or goes under the continental plate
What is likely to form where oceanic crust is subducted under continental crust?
because oshieotic crust is under Mantle is thicker
Subduction zones and what type of boundary do they represent?
Subduction zones represent convergent boundaries, where oceanic crust is being subducted under continental crust, or under a less dense oceanic crust.
When a more dense oceanic plate sinks under continental plate?
This is called a destructive plate boundary. It occurs due to the fact that the oceanic crust is far denser than the continental crust. As a result it subducts into the mantle and is incenerated. Hope it helped:)
Where are the elder parts of the ocean floor located?
Oceanic crust is created at mid-ocean ridges and (through the creation of new oceanic crust) is pushed toward a convergent plate boundary where it is subducted. So the oldest oceanic crust would be located at a convergent plate boundary where the oceanic crust is being subducted under continental crust.
What type plate margin are ocean trenches associated with?
Convergent plate margins where oceanic crust is being subducted under continental crust.
