Geologists and geophysicists split the Earth up into different layers. They do this based on various properties.
One system is dependent on the composition of the material (i.e. it's chemistry). If you use this system, then the Earth is split broadly into the crust, upper and lower mantle and the outer and inner core.
Another system is based on the mechanical properties of the Earth (e.g. how it responds to stress). In this system, the Earth is split into the lithosphere, asthenosphere, mesosphere and outer and inner core.
The oceanic crust is composed of mafic (magnesium and iron rich rocks) such as basalt and gabbro that have formed from the partial melting of the material that forms the upper mantle. As such they have differing chemical properties and so are classed as differing layers.
The lithosphere is that portion of the Earth which responds to stress in a brittle manner. It is formed of the crust AND the upper mantle as they both meet the criteria for failing in a brittle manner (and so have the same mechanical properties) even though they have differing compositions. As such they are described as a single mechanical layer, even though they are part of different compositional layers.
What else can I help you with?
How is a continential listhophere different from a oceanic lithoshere?
There is only a slight difference between crust and lithosphere. The difference is that the lithosphere is part of the Earth that encompasses.
What Lithosphere is made of?
The lithosphere is composed of oceanic crust (mostly basalt)
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 the name of the outerlayer of the lithosphere?
The crust is the outer layer of the lithosphere.
What earth layer is above the lithosphere?
The Earth layer known as the lithosphere consists of the crust and uppermost mantle. There is no solid layer above the lithosphere.
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.
How is a continential listhophere different from a oceanic lithoshere?
There is only a slight difference between crust and lithosphere. The difference is that the lithosphere is part of the Earth that encompasses.
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.
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.
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.
What Lithosphere is made of?
The lithosphere is composed of oceanic crust (mostly basalt)
What the lithosphere made of?
The lithosphere is composed of oceanic crust (mostly basalt)
What is the lithosphere made of the?
The lithosphere is composed of oceanic crust (mostly basalt)
What types of crust can be found in the lithosphere?
The lithosphere can have two main types of crust: continental crust and oceanic crust. Continental crust is thicker, older, and less dense than oceanic crust. Oceanic crust is thinner, younger, and denser, primarily composed of basaltic rocks.
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.
The boundary between continental crust and oceanic crust occurs at the base of the?
The boundary between continental crust and oceanic crust occurs at the base of the lithosphere. This boundary is known as the Mohorovičić discontinuity, or Moho. It separates the less dense continental crust from the more dense oceanic crust below.
