The most abundant element in both the Earth's inner core and outer core is iron. It makes up about 85% of the Earth's core composition.
Iron makes up most of the Earth's core.
The element that makes up most of the earths CORE is iron.
Iron is the primary element that makes up most of Earth's core, both the inner and outer cores. This iron is primarily in a liquid state in the outer core and a solid state in the inner core due to high pressures and temperatures.
Both the Earth's and the Moon's cores are composed of iron and nickel. However, the Moon's core is smaller, making up about 2-4% of its total mass, while the Earth's core makes up about 32% of its total mass. Both cores are also believed to be solid due to the immense pressure at their centers.
Iron.
32%
The Earth's core makes up about 15% of the planet's total mass.

The Earth's core makes up about 15 of the planet's total volume.
The mantle layer of the Earth makes up the majority of its mass. It is a region of hot, solid rock that lies between the core and the crust.
The Earth's core is primarily composed of iron and nickel. The inner core is believed to be solid, while the outer core is thought to be in a liquid state. The outer core makes up about 30% of the Earth's core, while the inner core makes up the remaining 70%.
