Inner Core learned this in 5th Grade
Outer core - predominately liquid iron and nickel. Inner core - predominately solid iron and nickel.
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 inner core is made out of iron and nickel and it is a solid.
The outer core is made up of liquid iron and nickel.
The core of the Earth consists mostly of iron and nickel. It is divided into the outer core (liquid iron-nickel alloy) and the inner core (solid iron-nickel alloy).
The inner core is made out of iron and nickel and it is a solid.
The layer of the Earth made up of solid nickel and iron is the inner core. It is the Earth's innermost part, consisting mainly of an iron-nickel alloy and playing a key role in generating the planet's magnetic field.
solid iron and nickel
It is solid iron and nickel.
The interior core of the Earth is a solid sphere composed of mostly iron and nickel. It is divided into an inner and outer core, with the outer core composed of liquid iron and nickel. The core plays a critical role in generating Earth's magnetic field.
The outer core is a liquid, composed mostly of iron and nickel.
The outer core of the Earth is a liquid layer composed mostly of molten iron and nickel. This layer is responsible for generating the Earth's magnetic field through the movement of conducting materials.
