- it's a sphere with a radius of about 1230 km
- it's made of iron
- it has a temperature of about 5500ºC (above melting point for iron), but is solid due to the pressure it is under
- it has a density of 13500 kg per cubic metre
- Seismic waves move through it faster from North to South than from equator to equator, suggesting an anisotropic quality
- computer simulations suggest that it is a single crystal of iron (Steinle-Neumann, Stixrude, Cohen - 2004)

How is the inner core and outer core different from each other?
The outer core is liquid, the inner core is solid The outer core surrounds the inner core The outer core is iron-rich, the inner core is iron-rich and nickel-rich There is more pressure acting on the inner core The inner core is hotter

Are the inner and outer core of earth the same?
No. The inner and outer core are both composed primarily of iron and nickel, but the outer core is liquid and surrounds the inner core. The inner core is the innermost layer of Earth and is kept solid by the enormous pressure.
What dense center of earth is made of solid iron and nickel?
There are two parts to core at the center of the Earth.the outer core is made of liquid iron and nickel and the inner core is made of solid iron and nickel.The inner core is solid from all off the pressure pushing down on it.
