Earths outer core and inner core are both inferred to be?

The inner core is a solid and the outer core is liquid.  Although the inner is hotter, the pressure is much more intense.  This keeps it a solid because melting temperature goes up with pressure.  Since the outer core is under less pressure it is assumed to be in a liquid state.  This information has been attained by doing geophysical surveys.  Based on the speed at which waves pass through these substances, a density and composition can be inferred.

Could be. There is so far no way to know the temperature of the earth's core. We know from drilling that the temperature increases about 1 degree Fahrenheit for every 60 feet in depth. Of course, there is considerable variation in this from region to region, since it depends on the thickness of the crust, volcanic activity, ocean depth, etc. Anyway if you extrapolate that towards the core, it would give you an answer much greater than 12,000 degrees F. Most sources estimate about 7500 Kelvin or 13,040 F. We can attempt to model the core to calculate the temperature but since we don't know for sure what it is made of, and cannot reproduce the extreme pressure, it is hard to really know the temperature.

The presence of the Earth's iron core. If you want to take a crack at the theory about how the field is created...here it is...

If you are talking about the core of the Earth or other planet, it is helpful but not complete. Scientists use other things as well (like sound transmission rates) to analyze the Earth's core. But they were probably the primary creators of the core a long time ago.

The interior of the Earth reaches temperatures of 5650 ± 600 kelvins [3] [4]. The planet's internal heat was originally generated during its accretion (see gravitational binding energy), and since then additional heat has continued to be generated by the decay of radioactive elements such as uranium, thorium, and potassium. The heat flow from the interior to the surface is only 1/20,000 as great as the energy received from the Sun.

Stated here:\n\nhttp://www.windows.ucar.edu/tour/link=/earth/Interior_Structure/interior.html&edu=high\n\nThe Earth's core heats to about 9000 degrees farenheit.  (if you have a different number, use that.)\n\nTo change Farenheit to Kelvin, you use the formula:\n\n\nK = (°F + 459.67) / 1.8\n\nso plugging in 9000 for farenheit, if my calculations are correct, the Earth's core should be about 5255.37 K

I thought there were four unless you dont count the core....\norder from outer to inner:\ncrust\nmantle\ncore\ninner core\nthat what you looking for?

The Earth consists of several atmospheric, hydrologic, and mainly geologic layers. Its components are the atmosphere, the hydrosphere, the crust, the mantle, and its core. The biosphere is a tiny layer in this composition and is usually not considered part of the physical layers of the Earth.\n\nThe geologic component layers of the Earth are located at the following depths below surface:\n\n0 to 60 km - Lithosphere (locally varies between 5 and 200 km) \n0 to 35 km - Crust (locally varies between 5 and 70 km) \n35 to 60 km - Uppermost part of mantle \n35 to 2890 km - Mantle \n100 to 700 km - Asthenosphere \n2890 to 5100 km - Outer core \n5100 to 6378 km - Inner core \n\nArea:\n\nTotal: 510.073 million km2 \nland: 148.94 million km2 \nWater: 361.132 million km2 \nNote: 70.8 % of the world's surface is covered by water, 29.2 % is exposed land \nLand boundaries: the land boundaries in the world total 251,480 km (not counting shared boundaries twice)\n\nCoastline: 356,000 km\n\nMaritime claims: see United Nations Convention on the Law of the Sea\n\nLand use\nArable land: 10% \nPermanent crops: 1% \nPermanent pastures: 26% \nForests and woodland: 32% \nUrban areas: 1.5% \nOther: 30% (1993 est.) \nIrrigated land: 2,481,250 km2 (1993 est.)\n\n\nContiguous zone: 24 nautical miles (44 km) claimed by most, but can vary \nContinental shelf: 200 m depth claimed by most or to depth of exploitation; others claim 200 nautical miles (370 km) or to the edge of the continental margin \nExclusive fishing zone: 200 nautical miles (370 km) claimed by most, but can vary \nExclusive economic zone: 200 nautical miles (370 km) claimed by most, but can vary \nTerritorial sea: 12 nautical miles (22 km) claimed by most, but can vary \nNote: boundary situations with neighboring states prevent many countries from extending their fishing or economic zones to a full 200 nautical miles (370 km) \n42 nations and other areas are completely landlocked (see list of landlocked countries)

None we know of, but keep in mind that the PRESSURE at the earth's core is greater than any pressure we have been able to reproduce, so we don't know for sure the behavior of melting points there. It may be no different. The highest known melting point is for graphite at 6,646.5 F. That's about half the estimated temperature of the core.

Yes, there is a complex relationship.\n\nThe poles of the Earth's magnetic field actually change their locations across geological time.\n\nHowever, it's speculated that the Earth's magnetic field may be caused by a flow of liquid iron in the Earth's outer core, which might be affected in part, but not only, by Earth's rotation.

the earth has a molten metallic core that's spinning...creates an em field

The earth's magnetism is a result of the fact that the core of the earth is liquid; as the earth spins around this liquid center, it creates polarity.

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.

Earth is composed of five main divisions or layers:\natmosphere, crust, mantle, outer core, and inner core.\n\nAstronomer: n. a scientist who specializes in astronomy, or the study of space.\n\nCrust: n. outer most layer of rock on Earth; the portion of Earth's surface with which we are most familiar; it is hard and brittle.\n\nMantle: n. the layer of the earth located below the crust, plastic in character and composed primarily of Fe and Mg.\n\nOuter core: n. the layer of the earth between the mantle and the inner core; theorized as liquid and comprised primarily of molten metal, mostly nickel.\n\nInner core: n. solid, inner-most portion of Earth.

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.
