What part of Earth is thought to be composed of iron and nickel?

Answer 1

The part of Earth that is thought to be composed primarily of iron and nickel is the Earth's core. The core is divided into two parts: the outer core, which is liquid, and the inner core, which is solid. The outer core is believed to be primarily composed of molten iron and nickel, while the inner core is thought to consist mainly of solid iron, with some nickel and possibly other elements.
