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.
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.
Yes. Well, more or less rigid.
The inner core Is solid and the outer core in liquid
Yes earths inner core is a dense ball of metal earths outer core is a layer of molten (melted) metal
no
The liquid layer of the Earth's core is called the outer core.
Depends if your talking about the inner core or the outer core: Outer core or mantle.
The solid inner and liquid outer core.
No the crust covers earths surface
no one knows
The outer core
The crust, mantle, inner core, and outer core.
asthenosphere outer core inner core and crust
the outer core is liquid; the inner core is solid
