The core is composed mostly of iron with lesser amounts of nickle and other elements

At the extreme pressure found in the core, this iron rich

The inner core and outer core are very similar

Their division is based on differences in mechanical strength

The outer core is a liquid capable of flow

The inner core, despite its high temperature is stronger than the outer core and behaves like a solid.
