is the mantle part of the lithosphere?

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. Although the rocks of the lithosphere are still considered elastic, they are not viscous.

Below the crust is the upper mantle, with the upper-most portion referred to as the asthenosphere. ... The lower mantle is in between the upper mantle and outer core of the earth. The lower mantle is the lower liquid portion of the mantle ranging from 400 miles below the surface to about 1,800 miles below the surface.

The lithosphere (litho:rock; sphere:layer) is the strong, upper 100 km of the Earth. The lithosphere is the tectonic plate we talk about in plate tectonics. The asthenosphere (a:without; stheno:strength) is the weak and easily deformed layer of the Earth that acts as a “lubricant” for the tectonic plates to slide over.

The lithosphere is the crust and the upper part of the mantle. The asthenosphere is a plastic like layer and continental plates move on top of it. The Mesosphere is the bottom of the mantle which is more rigid.

If we subdivide the Earth based on rheology, we see the lithosphere, asthenosphere, mesosphere, outer core, and inner core. However, if we differentiate the layers based on chemical variations, we lump the layers into crust, mantle, outer core, and inner core.

The upper mantle is made of olivine, pyroxene, and other crystalline minerals, while the lower mantle consists of silicon, magnesium, oxygen — it probably contains iron and other elements.

The lithosphere is the hard and rigid uppermost part of the mantle and crust. The asthenosphere is the soft layer in the lower part of the mantle. You just studied 13 terms!

The continental lithosphere is thicker (about 150 km). ... The oceanic lithosphere consists mainly of mafic crust and ultramafic mantle and is denser than the continental lithosphere, for which the mantle is associated with a crust made of felsic rocks.

The Earth consists of four spheres: the lithosphere, the hydrosphere, the atmosphere and the biosphere. The lithosphere consists of solid rock, soil and minerals. The hydrosphere consists of water in all its forms. The atmosphere is the layer of gases around the Earth.

The mantle lies between Earth's dense, super-heated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers (1,802 miles) thick, and makes up a whopping 84% of Earth's total volume.

The lithosphere also interacts with the atmosphere, hydrosphere, and cryosphere to influence temperature differences on Earth. Tall mountains, for example, often have dramatically lower temperatures than valleys or hills. ... The rocky lithosphere includes part of the upper mantle and crust.

The asthenosphere (from Greek ἀσθενής asthenḗs 'weak' + "sphere") is the highly viscous, mechanically weak and ductilely deforming region of the upper mantle of the Earth. It lies below the lithosphere, at depths between approximately 80 and 200 km (50 and 120 miles) below the surface.

The key difference between biosphere and lithosphere is that the biosphere is a part of the crust and atmosphere that support living matter while the lithosphere is the solid shell of the Earth that includes the crust and part of the uppermost mantle.

The mantle is divided into several layers: the upper mantle, the transition zone, the lower mantle, and D” (D double-prime), the strange region where the mantle meets the outer core. The upper mantle extends from the crust to a depth of about 410 kilometers (255 miles).

The temperature of the mantle varies greatly, from 1000° Celsius (1832° Fahrenheit) near its boundary with the crust, to 3700° Celsius (6692° Fahrenheit) near its boundary with the core. In the mantle, heat and pressure generally increase with depth.

The lithosphere-asthenosphere boundary, or LAB, represents the transition from hot, convecting mantle asthenosphere to overlying cold and rigid lithosphere. The oceanic lithosphere thickens as it cools over time, and eventually sinks back into the mantle at Earth's so-called subduction zones.

The Earth has an outer solid layer called the crust, a highly viscous layer called the mantle, a liquid layer that is the outer part of the core, called the outer core, and a solid center called the inner core. ... Between the Earth's crust and the mantle is a boundary called the moho.
