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
What else can I help you with?
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.
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.
Where is the old lithosphere destroyed?
earthquake ...
Is the lithosphere thinner under the oceanic or continental crust?
The lithosphere is generally thinner under oceanic crust compared to continental crust. Oceanic lithosphere is typically around 5-10 kilometers thick, while continental lithosphere can be up to 200 kilometers thick. This difference is due to variations in temperature and composition between the two types of crust.
Why is oceanic lithosphere subducted during and oceanic continental collision where as the continental plate is not?
Oceanic lithosphere is denser than continental lithosphere, so it is more likely to be subducted during a collision. The downward force exerted by the dense oceanic plate causes it to sink beneath the less dense continental plate. Furthermore, oceanic lithosphere is typically thinner and more malleable, making it easier to be forced beneath the continental lithosphere.
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 sinks beneath continental 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 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.
What is 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 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.
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.
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.
What is intertidal zone as it relates to oceanic lithosphere?
The intertidal zone is not related to the oceanic lithosphere because it is located on the continental shelf.
