Oceanic lithosphere is primarily destroyed at subduction zones, where one tectonic plate is forced beneath another into the mantle. This process occurs at convergent plate boundaries, often resulting in the formation of deep ocean trenches. As the oceanic plate subducts, it melts and contributes to volcanic activity and the recycling of materials back into the Earth's interior.
What else can I help you with?
Is oceanic lithosphere destroyed at a transform fault boundary?
No, oceanic lithosphere is not destroyed at a transform fault boundary. Transform boundaries involve horizontal sliding of plates past each other, causing lateral movement rather than creation or destruction of lithosphere.
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.
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.
Is lithosphere crust destroyed in convergent boundaries?
Yes, in convergent boundaries, lithosphere crust can be destroyed. When two tectonic plates collide, typically an oceanic plate subducts beneath a continental plate or another oceanic plate, leading to the bending and melting of the subducted crust. This process can result in the formation of deep ocean trenches and volcanic arcs, effectively recycling the lithosphere into the mantle.
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.
Is oceanic lithosphere destroyed at a transform fault boundary?
No, oceanic lithosphere is not destroyed at a transform fault boundary. Transform boundaries involve horizontal sliding of plates past each other, causing lateral movement rather than creation or destruction of lithosphere.
Oceanic lithosphere is destroyed at-?
Oceanic lithosphere is destroyed when it is subducted at a convergent plate boundary and forced into the mantle where it melts. You shouldn't use the internet to look up answers on a test. You should use your notes and textbook! DW Thanks for the answer but um, What about people in online school, where the only "textbook" you get is an agenda? yeah the awnser for Gradpoint is Convergent Boundary

Why does oceanic lithosphere sink beneath continental lithosphere at convergent boundary's?
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.

What is the oceanic lithosphere?
The lithosphere is composed of crust and hard upper mantle. The oceanic lithosphere would be hard upper mantle and basaltic oceanic crust.

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.
How is continental lithosphere different oceanic lithosphere?
Continental lithosphere is thicker and less dense than oceanic lithosphere. Continental crust is primarily composed of granitic rock while oceanic crust is composed primarily of basaltic rock.
Does continental lithosphere contain more mafic rocks than oceanic lithosphere?
No, oceanic lithosphere contains more mafic rocks compared to continental lithosphere. Oceanic lithosphere is mainly composed of basalt, which is a mafic rock, whereas continental lithosphere is composed of a variety of rock types, including granitic rocks which are more felsic in composition.
