The inner core of the Earth is made of solid nickel and iron, but mostly nickel. Wouldn't you think it was a liquid, or even a gas, because it's so extremely hot in the core? Actually, it's solid because there's so much pressure on it from the rest of the Earth and the atmosphere. Talk about having the "weight of the world on you". ;)
The Crust is in solid form of matter. It is the earth's hard outer shell which is composed of silicon, aluminum, calcium, sodium and potassium.
Liquid
The liquid layer of the Earth's core is called the outer core.
After the lithosphere is the asthenosphere, then comes the lower mantle. After that is the outer core, and then is the inner core.
The earths magnetic field results from deep in the earths core. Magnetic conduction from within the earths core is believed to be the cause of this.
They show that the outer core of the Earth is liquid while the inner core is solid.
There is no "purpose"; the density of the materials in the outer core are less pressured and spin slower than the inner core. NOTE: the inner core spins faster than the outer, creating Earth's magnetic field.
Soild
The state of matter the outer core is, is liquid.
cool stuff
the inner core is solid state and the outer core is liquid state

crust = solid mantle = solid soft enough to flow though outer core = liquid iron inner core = solid iron
In a liquid state.
Both! The outer core is in a liquid state and the inner core is a solid. Both the inner and outer core are formed mainly of iron and nickel.
