Describe different layers in the lithosphere
Answers
Answer:
The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth's structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below. There are two types of lithosphere: oceanic lithosphere and continental lithosphere.
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 is composed approximately of a 20- to 35-mile layer of light granitic crust underlain by a 60- to 80-mile layer of heavy mantle peridotite . Recall that these layers together form a tectonic plate.

Earth can be divided into three main layers: the core, the mantle and the crust. Each of these layers can be further divided into two parts: the inner and outer core, the upper and lower mantle and the continental and oceanic crust. Both the inner and outer core are made up of mostly iron and a little bit of nickel.
Lithosphere, rigid, rocky outer layer of the Earth, consisting of the crust and the solid outermost layer of the upper mantle. It extends to a depth of about 60 miles (100 km). It is broken into about a dozen separate, rigid blocks, or plates (see plate tectonics).

Lithosphere is defined as the rock and crust surface that covers the Earth. An example of lithosphere is the Rocky Mountain range in western North America.
The drawing begins at the earth's surface (sea level) and descends about 150 kilometers down. There are several layers shown, color coded brown and black, green, and reddish. The outermost brown and black layer, above the Moho (boundary between crust and mantle) is the crust.
