When the Earth was newly formed it was molten, and there were none of the separate layers that are present today.
As it cooled, the Earth became density stratified, with the densest material (predominantly iron) sinking to form the core, and the less dense material forming the mantle and crust.
Yes earths inner core is a dense ball of metal earths outer core is a layer of molten (melted) metal
Iron is the most abundant metal in the inner and outer core of the Earth.
No it is liquid
True, it is
No one invented metal. Metals are naturally occurring elements in the earths crust (and core)
Earth's core
The core is a dense chunck of metal that influence the earths magnetic field.
The molten iron and medals inside the earths core are the reasons for the earths magnetic core.
The earth's magnetic field is caused by convection currents in our core. The core is made out of iron, which is a magnetic metal.
The Earth's core is mainly made up nickel and iron. John Doe - Geology Major
Earth's greatest concentration of metal is found in its core, which is primarily composed of iron and nickel. This metallic core is believed to extend around 2,900 kilometers beneath Earth's surface.
no it is not true. there is solid iron and nickel in the Earths core
