The inner core.
The core of the Earth is defined by two layers: the inner core which is solid, and the outer core which is liquid. Both are composed primarily of iron with nickel.
The outer core is a liquid, composed mostly of iron and nickel.
The spherical solid core of the earth. It is an alloy composed mostly of nickel and iron.

The inner core is solid and composed mostly of iron.
The inner core is the only portion of the Earth which is considered to be composed of solid iron with nickel. The outer core surrounding it is a liquid iron-nickel alloy.Inner core
The outer core.
It is composed of an iron and nickel alloy, and is called the inner core.
the inner core
only liquid layer of the earth
An alloy of solid nickel and iron, mostly.
An alloy of solid nickel and iron, mostly.
The inner core.
The only liquid layer of Earth is the outer core, composed of liquid iron and nickel. Deep in the Earth's interior is an iron and nickel core. The center of that core is solid, but there is a layer a thousand miles or more think that is liquid. Above the core is mantle material that is not necessarily considered liquid, because it is so viscous. Earth has an outer solid crust.
