What layer of earth is made of molten iron and nickel?

Question:

What layer of earth is made of molten iron and nickel?

Geology:

Geology studies the Earth, as well as its physical components. These components can include rocks that are found on the surface of the Earth, as well as the layers that provide the Earth's inner structure.

Answer and Explanation:

The Earth consists of four different layers. From outer to inner they are ordered as follows: crust, mantle, outer core, and inner core. Of these four layers, the outer core is made from molten iron and nickel. The crust is a solid layer of rock, while the mantle is a churning layer of a mixture of molten rock. The inner core is a solid mass of metal due to the immense pressure created by the other layers.
