-   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.

- The shell is generated by the mantle from the inside. Pearls are made by clams, oysters and mussels when a grain of sand or other small irritant becomes painfully stuck in the mantle of the creature. The bivalve coats the irritant with the same material which is secreted to produce the inner lining of the shell.here are over 50,000 known species of Mollusks, which makes them second only to the Arthropods in invertebrate phylum size. Among the Mollusks are some of the most well known of invertebrate sea creatures, like snails, clams, mussels, squid, and octopods.

- 1 The mantle is made up of semi-molten rock called magma. 2  In the upper parts of the mantle the rock is hard, but lower down the rock is soft and beginning to melt. 3  The crust is the outer layer of the earth. 4  It is a thin layer between 0-60 km thick.he Earth is made up of four distinct layers: 1  The inner core is in the centre and is the hottest part of the Earth. 2  It is solid and made up of iron and nickel with temperatures of up to 5,500°C. 3  With its immense heat energy, the inner core is like the engine room of the Earth.

Mantle (geology) The interior of Earth, similar to the other terrestrial planets, is divided into layers of different composition. 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.

- The Earth's mantle is a roughly 1,800 mile (2,900 km) thick shell of compressed and heated rock, beginning below the Earth's crust (lithosphere), which extends 3.1 miles (5 km) below the ocean floor and 19 to 31 miles (30 to 50 km) below the continents.he Earth’s crust only comprises 1% of the planet’s total composition. The mantle is comprised of four separate layers: the upper mantle, transition zone, lower mantle, and anomalous core. Earth's mantle is the layer directly below the Earth's crust.

Mantle (geology) Mantle (geology) The mantle is a layer inside a terrestrial planet and some other rocky planetary bodies. For a mantle to form, the planetary body must be large enough to have undergone the process of planetary differentiation by density. The mantle is bounded on the bottom by the planetary core and on top by the crust.

Mantle (geology) Two main zones are distinguished in the upper mantle: the inner asthenosphere composed of plastic flowing rock of varying thickness, on average about 200 km (120 mi) thick, and the lowermost part of the lithosphere composed of rigid rock about 50 to 120 km (31 to 75 mi) thick.he 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.

Plate Tectonics Earth's Crust and Layers. Planet Earth is made up of several layers of crust, but the three main layers are the mantle, the core, and the crust. The core is the center of earth made up on an iron-nickel alloy that has the same tempurature as the sun. The mantle is the layer above the core, seperating the inner and outer mantles.

Mantle (geology) The mantle is bounded on the bottom by the planetary core and on top by the crust. The terrestrial planets (Earth, Venus, Mars and Mercury), the Moon, two of Jupiter's moons (Io and Europa) and the asteroid Vesta each have a mantle made of silicate rock.

- Think of the mantle like a peanut butter sandwich. You have the two pieces of bread and the peanut butter between them. In the mantle, we have two layers of solid rock with heated flowing rock between them.Next is the outer core. This is about 3,000 miles beneath the Earth’s surface. The outer core consists of super-heated liquid molten lava.

What is the Earthâs Mantle Made Of? The upper part of the lithosphere is the Earth’s crust, a thin layer that is about 5 to 75 km (3.1 to 46.6 mi) thick, which is separated from the mantle by the Mohorovicic discontinuity (or “Moho”, which is defined by a sharp increase downward in the speed of earthquake waves).

What Is the Earth's Lower Mantle Made Of? Quick Answer. Earth's lower mantle is made up of mantle-crust that consists of aluminum, silicon, magnesium, calcium, oxygen and iron. These elements in the lower mantle account for 72.9 percent of the entire mass of the Earth's mantle and about 50 percent of the planets entire mass. The lower mantle is directly underneath Earth's upper mantle and stretches from 416.319 to 1809.976 miles below the surface.

- Between the iron core of a planet and the rocky crust is the mantle. It is made largely of dark green to black minerals including olivine, pyroxene, spinel and garnet. Pallasites are a rare and beautiful type of meteorite, made of a nickel iron alloy studded with fragments of olivine.

- Making the world better, one answer at a time. Earth's lower mantle is mainly made of a toothpaste-like substance consisting of super-heated rocks and minerals.

mantle 3. mantle-the layer of the earth between the crust and the core. layer-a relatively thin sheetlike expanse or region lying over or under another. geosphere, lithosphere-the solid part of the earth consisting of the crust and outer mantle.lower mantle-the deeper part of the mantle.t consists mainly of silicate minerals and has an upper, partially molten part and a lower, solid part. The upper mantle is the source of magma and volcanic lava. 2. The layer of soft tissue that covers the body of a clam, oyster, or other mollusk and secretes the material that forms the shell.

The Earth's Layers Lesson #1 Finally, we would reach the Earth’s inner core. 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. Many geologists believe that the mantle flows because of convection currents.

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.

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.

- The bottom layer of the outer mantle is tough liquid iron and magnesium silicate rock, and the top layer is iron and magnesium silicate rock that is stiffer because the temper … ature is cooler. 1 person found this useful.

- Layers of the Earth. 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.The crust found underneath continents is 3 times thicker than the crust underneath the oceans.he first 50 miles of the mantle are believed to consist of very hard rigid rock. The next 150 miles or so is believed to be super-heated solid rock. Below that for the next several hundred miles, the Earth mantle is once again made up of very solid and sturdy rock materials.
