What are the 3 components of lithosphere?
Lithosphere The solid part of the earth. It consists of three main layers: crust, mantle and core.
What is the lithosphere composed of quizlet?
The lithosphere is: composed of the entire crust and the uppermost mantle. a layer of low rigidity that separates the rigid lithosphere from the rigid mantle.
What are the main elements in the lithosphere?
1. Oxygen, aluminum, calcium, iron, and silicon are the most abundant elements in Earth's lithosphere.
What is the lithosphere divided into?
The lithosphere can be divided into oceanic and continental lithosphere. Oceanic lithosphere is associated with oceanic crust (having a mean density of about 2.9 grams per cubic centimetre or 0.10 pounds per cubic inch) and exists in the ocean basins.
What is lithosphere quizlet?
lithosphere. the outer part of the Earth, consisting of the crust and upper mantle, approximately 100 km (62 miles) thick. crust. the thin and solid outermost layer of earth above the mantle. tectonic plates.
Which best describes lithosphere?
The correct answer is Crust and Upper mantle. It is the outer solid part of the earth, including the crust and uppermost mantle. It is about 100 km thick, although its thickness is age-dependent. The lithosphere, that is the rigid outer part of the earth with thickness varying between 10-200 km.
What are the two main components of the lithosphere?
The lithosphere is composed of both the crust and the portion of the upper mantle that behaves as a brittle, rigid solid..
How many plates is the lithosphere composed of?
The crust and solid upper part of the mantle make a layer called the lithosphere which is broken into 7 major slabs called tectonic plates.
What kind of rock is the lithosphere made of?
The lithosphere is broken into large pieces called plates, which are made up of either seafloor lithosphere (mostly basalt) or continental lithosphere (less dense rocks, like granite).
What layer of the Earth is composed of material of the highest density?
The inner core is at the center of the Earth because it is the densest, made of solid iron and nickel.
Where is the lithosphere found quizlet?
Lithosphere: →layer of the Earth made up of the crust and the rigid part of the upper mantle.
How lithosphere is formed?
Oceanic lithosphere forms at midocean ridges, where hot magma upwells, and then cools to form plates as the material moves away from the spreading center. As the plate cools, heat flow decreases and the seafloor deepens (Fig.
Is the lithosphere made of magma?
The magma, comes from the other part of the lithosphere. It's released from the upper portion of the mantle. The lithosphere's responsible for the renewal of the Earth's surface.
What is the lithosphere and describe its characteristics?
Lithosphere is the solid crust or the hard top layer of the earth. It is made up of rocks and minerals. It is covered by a thin layer of soil. It is an irregular surface with various landforms such as mountains plateaus desert plains valleys etc.
What is each layer of the Earth made of?
The earth is made up of three different layers: the crust, the mantle and the core. This is the outside layer of the earth and is made of solid rock, mostly basalt and granite….The core.

What are the two components of the lithosphere quizlet?
The lithosphere is the tectonic plate and consists of crust (continental and oceanic), Moho line, Upper Mantle Rigid. The asthenosphere is where the convection currents drive the plates apart and consist of Upper Mantle flowing.
How is the lithosphere formed?
Oceanic lithosphere forms at midocean ridges, where hot magma upwells, and then cools to form plates as the material moves away from the spreading center. As the plate cools, heat flow decreases and the seafloor deepens (Fig. 3).
What are the two components of the lithosphere?
The lithosphere is composed of both the crust and the portion of the upper mantle that behaves as a brittle, rigid solid.
What is the structure and composition of the oceanic lithosphere?
The oceanic lithosphere is composed primarily of mantle peridotites and magmatic rocks that are the result of the melting of these mantle rocks: gabbro, diabase and basalt.
