- The upper mantle is made of peridotite and eclogite rock and extends from the Moho to a depth of 400km. The earth's crust and uppermost mantle together form the lithosphere. The lithosphere makes up the plates of plate tectonic theory. The lithosphere averages about 70 kilometers thick beneath continents.

The Earth's Layers Lesson #1 The inner core extends another 900 miles inward towards the center of the Earth. It is believed that this inner core is a solid ball of mostly iron, and nickel. The mantle is made of much denser, thicker material, because of this the plates float on it like oil floats on water.

-   The earth's mantle is not made of metal but is a mixture of many somewhat molten rocks, most as oxides, meaning the mantle may be more oxygen than metal. The metals it … has the most of are magnesium, iron, and aluminum. There's also lots of silicon, which is not really a metal. 6 people found this useful.

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.he mantle lies between the core below and the crust above. The terrestrial planets (Earth, Venus, Mars and Mercury), Earth's Moon, two of Jupiter 's moons (Io and Europa) and the asteroid Vesta each have a mantle made of silicate rock.

Layers Of The Earth For Kids | Crust, Mantle And Core However, these layers are further broken down into sub-layers. The crust is made up of two sub-layers; oceanic crust and continental crust. The mantle is divided into two portions; upper mantle and lower mantle. Upper mantle is further sub-divided into two layers; lithosphere and asthenosphere. The core consists of two regions; outer core and inner core. So let’s have a quick overview of each of these layers in Layers of the Earth for Kids.

- The Earth is made up of four distinct layers: The inner core is in the centre and is the hottest part of the Earth. It is solid and made up of iron and nickel with temperatures of up to 5,500°C. With its immense heat energy, the inner core is like the engine room of the Earth. The outer core is the layer surrounding the inner core. It is a liquid layer, also made up of iron and nickel. It is still extremely hot, with temperatures similar to the inner core. The mantle is the widest section of the Earth.

- 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.et's start from the inside and work our way out. Earth has a core, but this is really two distinct parts: the inner core and the outer core. Both parts of the core are made up of mostly iron and some nickel. The difference is that in the inner core, those minerals are solid and in the outer core, they're liquid.

Earth's crust Earth's crust is Earth's hard outer layer. It is less than 1% of Earth's volume. The crust is made up of different types of rocks: igneous, metamorphic, and sedimentary rocks. Below the crust is the mantle. The upper part of the mantle is made up of peridotite, a rock denser than rocks common in the crust. The crust and the upper mantle make up the lithosphere.

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.Mantle rock is higher in magnesium and iron than the crust.Rocks in the upper mantle are composed of the minerals olvine, garnet, spinel and pyroxene. With increasing depth, some of these minerals become unstable and are replaced by mineral polymorphs which have the same chemical composition, but different structures.he mantle may be very close to the melting point of the rock which composes it, or even partially melted. Mantle rock is higher in magnesium and iron than the crust. Rocks in the upper mantle are composed of the minerals olvine, garnet, spinel and pyroxene.

The Earthâs Mantle The first 50 miles (80km) of the mantle are believed to consist of very hard, rigid rock. The next 150 miles (241km) or so are believed to be super-heated solid rock that due to the heat energy is very weak. Below that for the next several hundred miles, the Earth's mantle is believed to once again be made up of very solid and sturdy rock materials. All Content Copyrighted 1998- 2015©.

- 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 Earth Made Of? The mantle under the crust is about 1,800 miles deep (2,890 km). It is composed mostly of silicate rocks rich in magnesium and iron. Intense heat causes the rocks to rise. They then cool and sink back down to the core. This convection — like a lava lamp — is believed to be what causes the tectonic plates to move.

- The earth is made up of layers (crust, mantle, outer core, and inner core). Each one has a unique make-up to it. Crust. This is the outer layer of the Earth about 10 miles or so thick. Mostly made up of rock and loose material.he next layer beneath the crust is called the mantle. It extends to a depth of approximately 1,800 miles and is made of a thick solid rocky substance that represents about 85% of the total weight and mass of the Earth. The first 50 miles of the mantle are believed to consist of very hard rigid rock.

What is the Difference Between a MD and DO FACS? While the MD designation is the more typical designation for a plastic surgeon, I know of some excellent plastic surgeons who are DOs as well. One of the basic requirements for choosing a plastic surgeon is to ensure that he/she is board certified by the American Board of Plastic Surgery.

Upper Mantle: Definition, Facts, Temperature & Composition A mantle is more than just that ledge over your fireplace where you put pictures and candles. To scientists, the mantle is an important and large part of the interior of the Earth. The Earth may seem like a giant ball of solid rock, but its interior is actually made up of layers. The center of the Earth is the core, and it is solid, kind of like the pit in a peach.

- 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.
