The Core

Inner Core

The centre of Earth - is solid and about 1,250 km thick. Even though temperatures reach 6000˚C the inner core pressures are so great that the nickel and iron cannot melt.

Outer Core

At almost 2,200 km thick the outer core is made of molten nickel and iron at ~4500˚C. The molten metal spins around as the earth rotates and is responsible for the earth’s magnetism.
