- The mantle is about 1800 miles (2900 km) thick, and is separated into the upper and lower sections. Large convective cells in the upper mantle circulate heat and drive plate tectonic processes of the crust. The crust and the solid portion of the upper mantle compose a layer called the lithosphere.

Crust, Mantle, Outer Core, and Inner Core - The mantle's state of matter is Solid. -The composition of Earth's mantle is molten/solid rock (magma). - The Outer Core is the second to last layer of the Earth. It is a magma like liquid layer that surrounds the Inner Core and creates Earth's magnetic field.

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.

Mantle plume A mantle plume is an upwelling of abnormally hot rock within the Earth's mantle. As the heads of mantle plumes can partly melt when they reach shallow depths, they are thought to be the cause of volcanic centers known as hotspots and probably also to have caused flood basalts. It is a secondary way that Earth loses heat, much less important in this regard than is heat loss at plate margins.

Mantle plume Mantle plume. A mantle plume is a mechanism proposed in 1971 to explain volcanic regions of the Earth that were not thought to be explicable by the then-new theory of plate tectonics. Some such volcanic regions lie far from tectonic plate boundaries, for example, Hawaii.

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.

- Definition. The upper mantle is defined as that part of the mantle between the crust and the phase transition of γ-olivine to perovskite. The total mass of the upper mantle is 1.06 × 10 24 kg, about a quarter of the total mass of the mantle. Its volume, 2.95 × 10 11 km 3, is a third of the total volume of the mantle. Until the discovery of a major transition near 660-km depth, the upper mantle was better known as Bullen’s “layer B,” extending to 400-km depth.

Noble gases in anhydrous mantle xenoliths from Tasmania in comparison with other localities from eastern Australia: Implications for the tectonic evolution The noble gas isotopic compositions observed in mantle-derived xenoliths from Tasmania indicate a heterogeneous SCLM, with contributions from a MORB-like component and a radiogenic component. Spatial variation in the noble gas isotopic compositions were not observed: there is no difference between the sides of the assumed Tasman Line.

Gas Giants Gas Giants. Gas giants are large planets that contain more than 10 times the mass of Earth, they are also known as the Jovian or Outer Planets. Their compositions are mostly gases, such as hydrogen, and small amounts of rocky material (mostly at their cores).

- Most of these gases originate in the mantle and are transported to the crust and surface by complex interactions with magma and rocks encountered along the way. In general, the gases are dissolved in the magma. At shallow depths, as pressure on the magma decreases, the gases leave the magma (exsolve).

Mantle (geology) The interior of Earth, similar to the other terrestrial planets, is chemically divided into layers. The mantle is a layer between the crust and the outer core. Earth's mantle is a silicate rocky shell with an average thickness of 2,886 kilometres (1,793 mi). The mantle makes up about 84% of Earth's volume. It is predominantly solid but in geological time it behaves as a very viscous fluid. The mantle encloses the hot core rich in iron and nickel, which makes up about 15% of Earth's volume.

- Summary. The mantle is a layer of the Earth between the crust and the core. The upper mantle starts below the crust and goes down to a depth of around 200 miles to the boundary with the lower mantle.The temperature of the mantle ranges from 900 degrees Fahrenheit near the crust to as high as 7000 degrees near the core.he center of the earth is the core and it is solid, kind of like the pit in a peach. The outer layer of the Earth is called the crust and is thin, like the skin of the peach. In between the two, in the meat of the peach, is the mantle, which can further be divided into the upper and lower mantle.

What is mechanical layers? - Outer core (liquid), 2900-5730km. - Inner core, 5730-6400km. The lithosphere is the outermost mechanical layer and is the most rigid layer of the Earth. The lithosphere consists of the crust, and some of the uppermost mantle. The lithosphere averages about 100 km thick. It is somewhat thicker beneath continents, and dramatically thinner under mid-ocean ridges.

- The Earth’s mantle, on which the crust is lying on, is not made of liquid magma.It is not even made of magma. The Earth’s mantle is mostly made of solid rock.The misconception of a liquid mantle arises from expressions like “a subducted tectonic plate sinks into the mantle” or “continental drift”, expressions that implicitly refer to the liquid element.he Earth’s mantle is mostly solid from the liquid outer core to the crust, but it can creep on the long-term, which surely strengthens the misconception of a liquid mantle.

What is the Earth's upper mantle made of? The uppermost mantle is connected to the crust and forms the asthenosphere, which composes Earth's tectonic plates. The bulk of the mantle is composed of extremely hot rock under enormous pressure. The mantle may be very close to the melting point of the rock which composes it, or even partially melted.

Gas mantle An incandescent gas mantle, gas mantle, or Welsbach mantle is a device for generating bright white light when heated by a flame. The name refers to its original heat source in gas lights which filled the streets of Europe and North America in the late 19th century, mantle referring to the way it is hung above the flame. Today it is still used in portable camping lanterns, pressure lanterns and some oil lamps [1].

Subtracting the iron in the core, we can calculate that the mantle is a mix of magnesium, silicon, iron, and oxygen that roughly matches the composition of garnet.

Mantle of the Earth Mantle of the Earth. the shell of the “solid” earth, located between the earth’s crust and its core. It occupies 83 percent of the earth (excluding the atmosphere) by volume and 67 percent by mass.t the base of the mantle is a layer less than 100 km thick in which the velocities of seismic waves do not increase with depth or even decrease slightly.
