Tectonic plates consist of the lithosphere,or the crust and the upermost mantle? Mechanically speaking, Seismologists define the Lithosphere as the hard & ridged outer ~100 km of the Earth. The Lithosphere includes the Crust (more on it below) and the uppermost (<1300 Celsius) brittle Mantle. Below the brittle Lithosphere (Crust+upper brittle Mantle) is the Astenosphere, a weak plastic layer within the upper Mantle below, the Astenosphere is defined as having a temperature >1300 Celsius.

The lithosphere consists of the heavy oceanic and lighter continental crusts, and the uppermost portion of the mantle mantle,portion of the earth's interior lying beneath the crust and above the core.ithosphere. the outer sphere of the “solid” earth, including the earth’s crust and the upper layer of the mantle (substratum). The lower boundary of the lithosphere runs above the asthenosphere. Until the 1960’s “lithosphere” was a synonym for the earth’s crust.

- The lithosphere is Earth's outermost layer, composed of rocks in the crust and upper mantle that behave as brittle solids. The rigid lithosphere sits on top of the asthenosphere, a layer of the mantle in which rocks are hot and deformable. 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).

- The lithosphere contains rocks, minerals, and soils. It is made up with more than 100 chemical elements, but most of them are rare. Only eight elementsoxygen (O), silicon (Si), aluminum (Al), iron (Fe), calcium (Ca), sodium (Na), potassium (K), and magnesium (Mg)constitute more than 99% of its volume.

Why is the lithosphere important to us?? Report Abuse. The lithosphere (from the Greek for rocky sphere) is the solid outermost shell of a rocky planet. On the Earth, the lithosphere includes the crust and the uppermost layer of the mantle (the upper mantle or lower lithosphere) which is joined to the crust. As the cooling surface layer of the Earth's convection system, the lithosphere thickens over time.

Lithosphere The lithosphere is the solid and rigid outer layer of our planet. It includes the crust and part of the upper mantle that contains rigid rocks. Beneath this layer is the asthenosphere where the rocks in this part of the upper mantle are not rigid.The rocks can flow like a liquid or break apart similar to silly putty.he continental crust contains a variety of rocks. They are igneous rocks, sedimentary rocks and metamorphic rocks that make up the rock cycle. Continental crust is lighter than oceanic crust which is made of basalt and gabbro. These rocks are derived from the upper mantle.

- It is the lithosphere and the asthenosphere that are the parts of the surface moving when we talk of continental drift. The lithosphere is outer portion of the Earth. It is composed of the oceanic and continental crust, along with the rigid upper mantle. The asthenosphere is the plastic like upper mantle directly below the lithosphere where rock can move, bend, and deform without breaking. Below that, the mantle become more fluid and is the major part of the volume of the Earth.

What is the lithosphere and asthenosphere? Best Answer: lithosphere is the solid outermost shell of a rocky planet. On the Earth, the lithosphere includes the crust and the uppermost layer of the mantle (the upper mantle or lower lithosphere) which is joined to the crust. for more see http://en.wikipedia.org/wiki/Lithosphere...sthenosphere is the region of the Earth between 100-200 km below the surface — but perhaps extending as deep as 400 km — that is the weak or soft zone in the upper mantle.

- The asthenosphere is a part of the Earth's upper mantle. The asthenosphere lies underneath the lithosphere which is the Earth's rigid plates (plate techtonics). In a sense, the lithosphere floats on top of the asthenosphere. It is dense, and consists of some partially molten rock. It is considered a low velocity zone.

A lithosphere ([lithos] for rocky, and [sphaira] for sphere) is the rigid, outermost shell of a rocky planet, and can be identified on the basis of its mechanical properties. lithosphere n: the solid part of the earth consisting of the crust and outer mantle [syn: {geosphere}].

Asthenosphere Earth cutaway from core to crust, the asthenosphere lying between the upper mantle and the lithospheric mantle (detail not to scale). 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 Lithosphere-Asthenosphere boundary is usually referred to as LAB. The asthenosphere is generally solid, although some of its regions could be melted (e.g. below mid-ocean ridge).

- By Andrew Alden. The lithosphere is the brittle outer layer of the solid Earth. The plates of plate tectonics are segments of the lithosphere. The lithosphere is basically the layer of the Earth that is strong enough to flex rather than flow.

The Lithosphere: Definition & Composition Let's look at the physical characteristics of the compounds that make up the lithosphere. The lithosphere is made up of rocks from two of the earth's major layers. It contains all of the outer, thin shell of the planet, called the crust, and the uppermost part of the next-lower layer, the mantle. The thickness of the lithosphere varies; it's thickest below the continents and thinnest at the mid-ocean ridges, raised areas of the seafloor where new seafloor crust is formed.

lithosphere The outer part of the Earth, consisting of the crust and upper mantle. It is about 55 km (34 mi) thick beneath the oceans and up to about 200 km (124 mi) thick beneath the continents. The high velocity with which seismic waves propagate through the lithosphere suggests that it is completely solid. Compare asthenosphere, atmosphere, hydrosphere.

lithosphere The lithosphere includes the Earth's crust and the uppermost part of the mantle. The lithosphere's thickness varies depending on whether you measure the thin new crust on the ocean floor or the old crust of an established land mass. The Earth's lithosphere is broken into continental plates that move over time. Slight movements in the lithosphere can cause earthquakes when the plates bump against each other. Litho is from the Greek word lithos, meaning stone. Sphere is from the Greek word sphaira, meaning globe or ball. The solid outer crust of any celestial body can also be called the lithosphere. Scientists use robots to examine the lithosphere on Mars.

plate tectonics noun, Geology. 1. a theory of global tectonics in which the lithosphere is divided into a number of crustal plates, each of which moves on the plastic asthenosphere more or less independently to collide with, slide under, or move past adjacent plates.

What is the asthenosphere? The lithosphere extends from the Earth's surface to … a depth of between 100 to 200 km. The asthenosphere is that part of the Earth which is viscous and undergoes ductile deformation and convection on a geological time scale. It is part of the upper mantle and is approximately 600 km thick laying below the lithosphere at a depth of around 100 to 200 km and it's base is around 700 km deep.
