The core is made up of Iron and Nickel.
The 3 main layers of earth (crust, mantle, core) are divided into crust, upper mantle, lower mantle, outer core, and inner core.
Well, It has about an Earth sized core made of rock material. The core is also surrounded by a layer of liquid that's possibly a water, methane and ammonia mixture. The core temperature is about 100 degrees Celsius.
Information about these regions is obtained from the travel of seismic waves, and from high pressure laboratory studies. The inner core is solid because of the intense pressure due to gravity. The outer core is of quite similar composition, but under lower pressure, it remains liquid. Both regions are believed to be mainly iron and nickel, though there will be significant quantities of other heavy metals as well, including radioactive ones. It is because of heat released by these radioactive materials that the outer core is molten. (and by conduction and convection to the magma. )
I think its the last one. The material is hotter and denser. I'm doing the assessment now. ^ Brinaq: K12 FTW! ^ Kiwi: Yeah K12 FTW!
Based on the physical properties of the earth;The core is divided into outer core and inner core.the liquid layer of the earth core is the outer core,while the inner core is solid.

Theories of the Earth's core composition are supported by meteorites that are composed of iron and nickel, similar to what is believed to be present in the Earth's core. This similarity suggests that meteorites could be remnants from the early solar system and provide clues about the Earth's core composition.
There is a large file on Jupiter's composition and other facts - in Wikipedia !
the outer core
The Earth's layers of rock are classified by their composition and physical properties. The main layers are the crust (continental and oceanic), mantle, and core (outer and inner). These layers are distinguished by differences in chemical composition, density, and temperature.
