Here is a chart of various estimates of the mantle's composition that have been made:\nhttp://www.mpch-mainz.mpg.de/~jesnow/Ozeanboden/2004/Lecture4/Composition.html\n\nThe answer in terms of minerals is (I quote) "The uppermost mantle is comprised of a peridotite with about 60% olivine 30% enstatite 6% clinopyroxene, 2% plagioclase and 2% spinel. At slightly greater depth, the plagioclase disappears and is replaced by spinel and clinopyroxene. Deeper still, garnet appears." from the above site. \n\nThe other thing you should realize is that while the earth's mantle may be 'plastic' it is not molten. From Wikipedia: "Although these temperatures far exceed the melting points of the mantle rocks at the surface, particularly in deeper ranges, they are almost exclusively solid. The enormous lithostatic pressure exerted on the mantle prevents them from melting."  From: http://en.wikipedia.org/wiki/Mantle_%28geology%29\n\nMagma coming from volcanoes actually originates in the asthenosphere, which is above the mantle.

About 1,800 miles beneath the surface, Earth's internal structure changes abruptly where the solid rock of the mantle meets the swirling molten iron of the outer core. \nBut the boundary between the core and the mantle may not be as sharply defined as scientists once thought. By analyzing earthquake waves that bounce off the core-mantle boundary, researchers have found evidence of a thin zone where the outermost core is more solid than fluid.\n\nThe existence of such "core-rigidity zones" -- small patches of rigid material within the fluid outer core -- has been suggested before, but this report marks the first time scientists have detected one.

No. In general, the inner planets of a solar system will be made up of heavy metals, while the lighter elements will be found in the outer planets. Jupiter, for example, has a core of liquid hydrogen.

Probably silicone and iron.   It's a friggin big rock.   Hollow it out a bit; near the center the gravity is probably near earths gravity.

middle layer would be mantle, center would be core.

Crust, Mantle and Core\nCrust \n\nScientists suspect that the average thickness of the Martian crust is about 30 miles (50 kilometers). Most of the northern hemisphere lies at a lower elevation than the southern hemisphere. Thus, the crust may be thinner in the north than in the south. \n\n\n \nThe surface of Mars was sampled for signs of life by the Viking 2 lander in 1976. A mechanical sampling arm dug the grooves near the round rock at the lower left. The cylinder at the right covered the sampling device and was ejected after landing. The cylinder is about 12 inches (30 centimeters) long. Image credit: NASA/National Space Science Data Center\n \nMuch of the crust is probably composed of a volcanic rock called basalt (buh SAWLT). Basalt is also common in the crusts of Earth and the moon. Some Martian crustal rocks, particularly in the northern hemisphere, may be a form of andesite. Andesite is also a volcanic rock found on Earth, but it contains more silica than basalt does. Silica is a compound of silicon and oxygen. \n\nMantle \n\nThe mantle of Mars is probably similar in composition to Earth's mantle. Most of Earth's mantle rock is peridotite (PEHR uh DOH tyt), which is made up chiefly of silicon, oxygen, iron, and magnesium. The most abundant mineral in peridotite is olivine (OL uh veen). \n\nThe main source of heat inside Mars must be the same as that inside Earth: radioactive decay, the breakup of the nuclei of atoms of elements such as uranium, potassium, and thorium. Due to radioactive heating, the average temperature of the Martian mantle may be roughly 2700 degrees F (1500 degrees C). \n\nCore \n\nMars probably has a core composed of iron, nickel, and sulfur. The density of Mars gives some indication of the size of the core. Mars is much less dense than Earth. Therefore, the radius of Mars's core relative to the overall radius of Mars must be smaller than the radius of Earth's core relative to the overall radius of Earth. The radius of the Martian core is probably between 900 and 1,200 miles (1,500 and 2,000 kilometers). \n\nUnlike Earth's core, which is partially molten (melted), the core of Mars probably is solid. Scientists suspect that the core is solid because Mars does not have a significant magnetic field. A magnetic field is an influence that a magnetic object creates in the region around it. Motion within a planet's molten core makes the core a magnetic object. The motion occurs due to the rotation of the planet. \n\nData from Mars Global Surveyor show that some of the planet's oldest rocks formed in the presence of a strong magnetic field. Thus, in the distant past, Mars may have had a hotter interior and a molten core.

The earth has an electromagnetic field that is generated by the earth's core.  The core is a ball of hot liquid iron and nickel spinning around, and the spinning of the metal generates the magnetic field. \nIt surrounds the earth, connecting to the earth at the north and south poles.\nIs that what you mean by "themagenet in earth not found in space?"\nIf that's not what you mean, perhaps you need to reword your question into more understandable English.

None!\n\nAtmosphere is made up of Nitrogen (78%), Oxygen (21%),Argon (0.9%) and other gasses e.g Carbon dioxide, Methane, Rare (inert) gases (0.1%)

There are a few main parts to the earth. The earth is like a tootsie pop: a hard crunchy exterior, and it is soft inside. They are in roughly concentric spheres. The main layers of the earth are called the crust, the mantle and the core. \n\nThe outside shell of the earth is called the crust. The crust is about 5-60 kilometers thick and forms about 1% of the volume of the earth. We live on the crust. \n\nUnder the crust is a very large part of the earth called the mantle. The mantle is about 84% of the volume of the earth. The mantle is about 2800 kilometers thick.\n\nInside the mantle, is the soft middle of the earth, called the core. The core is roughly a round ball, and is about 15% of the volume of the earth, and has a radius of about 3400 Km. \n\nOf course, one can get much more detailed, but this is enough to give you a start, so you can understand what you read on the internet.

mantle\nThe Mantle. It is divided into two parts. The upper portion, which is called the Asthenosphere, is a plastic like fluid. This is where the mantle convection currents occur. The rest of the mantle is made up of dense rock. The mantle is the thickest layer. Approximately 2900 km thick

The motion within the "liquid" outer core and mantle, would probably impart their motion onto the solid iner core

Like the Earth, Mercury has an iron core. But Mercury's core occupies proportionately more (3/4) of the planet's diameter than Earth's does (about half). You can think of Mercury as a metal ball the size of the Moon surrounded by about 700 kilometers (430 miles) of rocky crust. The large relative size of Mercury's core makes it the most iron-rich planet in the solar system, with iron accounting for 65-70% of the planet's mass. Mercury's abundance of iron resulted from its position near the Sun. When the planets were forming out of the same cloud of gas and dust as the Sun, the temperatures in the warm inner regions of the primordial solar nebula were so high that iron-rich minerals were just about the only ones that could condense into solids. Farther away from the Sun, other minerals could also condense. Thus the iron content of the rocky planets in the solar system decreases with increasing distance from the Sun.\n\nMercury's iron core may also be responsible for one of the most surprising findings from Mariner 10 — the planet's weak magnetic field, 100 times weaker than Earth's. Astronomers and geologists are still trying to figure out what causes Mercury's field. In the case of the Earth, rapid rotation of its molten iron core generates electrical currents which produce the Earth's magnetic field. But Mercury is so small, astronomers had assumed its core had cooled and solidified. Plus, it rotates too slowly to generate a magnetic field the way the Earth does. Or so they thought. Perhaps Mercury's core is still partially liquid, or perhaps the magnetic field is "left over'' from an earlier time when the iron core was molten. Astronomers continue to work on this puzzle.

no, it's solid iron, with a molten layer sorrounding it that revolves and creates our magnetic field.

I would believe that analogy to be inaccurate.  The inner core is more of a very dense, solid mass of mostly iron and with its spin, among other things, gives our Earth its magnetic field.  The outer core, while quite hot, I would not call it a ball of fire.  It is more in the state of fluid, plastic like state which churns and, and at its boundary, mixes with the mantle to some degree.  Our planets core is dense and hot, but not a ball of fire.

The Earth can be divided into three large sections: the mantle, inner core, and outer core. The inner core is at the center of the earth. The pressure and temperature of the earth increases as one moves closer to the center. The inner core of the earth is about 7000 degree Celsius.

Scientists believe that the outer core is a liquid made out of an iron-nickle alloy, and the inner core is a liquid that behaves like a solid, and is mostly made out of iron.
