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.
The solid inner and liquid outer core.
So far as science can deduce, it must be a solid.
No it is liquid
the outer core is liquid; the inner core is solid
The inner core Is solid and the outer core in liquid
The Inner Core is a liquid. Outer core: solid mantel: inbetween crust: solid
no the core of the earth is not solid its pretty much a liquid, since the middle of the earth is so hot, the core is like a lava substance.
The Inner (solid) and Outter (liquid) Core are made up of Nickel and Iron.
, a liquid outer core that is much less viscous than the mantle, and a solid inner core.
Soild
The core..............
iron and nickel is the answer and so is the inner core. the inner and the outer and together but the outer core is liquid and the inner core is solid
