Question

Differentiate oceanic lithosphere from a continental lithosphere

Answer 1

Answer:

Oceanic lithosphere :- Oceanic lithosphere consists mainly of mafic crust and ultramafic mantle (peridotite) and is denser than continental lithosphere, for which the mantle is associated with crust made of felsic rocks. Oceanic lithosphere thickens as it ages and moves away from the mid-ocean ridge.

Continental lithosphere :- The continental lithosphere consists of the continental crust and, typically, some nonconvecting part of the underlying upper mantle . In plate tectonics terms, the continental lithosphere is part of the rigid outer rind of the Earth, which is segmented into several major plates.

Answer 2

Answer:

it is not continental lithosphere or oceanic lithosphere , the outer most layer of earth-crust is divided into 2 parts continental crust and oceanic crust               The Oceanic crust is the uppermost layer of the oceanic portion of the crust.The crust and the solid mantle layer together constitute oceanic crust and it is mainly made up of silica {SI} and magnesium {MA} so it is often known as SIMA  . the  continental crust is  that underlies the continents and it is made up of silica {SI} alumina {AL} so they are known as SIAL. hope this is helpful
