It is thought to be mostly iron.
solid metal inner core
the inner core is made up of solid iron, the outer core is made out of molten metal, and the mantle is made up of solid it feels like Jello.
The outer core is the only molten layer of the Earth. == ==
No. Rather the core of mercury is made up of iron probably in a molten or liquid state.
Earth was largely molten when it was newly formed. The iron and nickel that now make up the core were the densest common materials, so they sank tot he center to form the core.
Oil does not cool the Earth's core as it is located far away from the core and would simply burn up due to the sheer heat. The Earth's core is made of molten metal which keeps a relatively constant temperature.
Yes. The Earth's outer core is made out of liquid. However, the inner core is made up of a metal compound.
Iron is the main ingredient.
The inner core of the Earth is composed of solid iron. The outer core is made up of molten metals, primarily a nickel-iron alloy.
Iron
The inner core is the solid part of the core
The inner and the outer core of the earth are made up iron and nikel mostly.
