iron
The element that makes up most of the earths CORE is iron.
scientists think that the earths core is made up of mostly iron, and contains smaller amounts of copper nickel.
The principle element found at the Earth's core is iron.
It makes up the majority of the molten core of the earth.
Iron is the primary element that makes up most of the Earth's core. It accounts for about 85% of the core's composition, with the rest likely being nickel in combination with some lighter elements.
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.
In terms of weight, iron makes up approximately 5% of the earths crust, the fourth most abundant element in the crust. However, remember Earth's Core is nearly all Iron.
no
Because of the difference/wavering in the earths magnetic field due to thwe fact the inner core is largely Iron....
Iron makes up most of the Earth's core.
