Temperature of the inner-core boundary of the Earth: Melting of iron at\n high pressure from first-principles coexistence simulations The Earth's core consists of a solid ball with a radius of 1221 Km,surrounded by a liquid shell which extends up to 3480 Km from the centre of theplanet, ...
Surrounding the inner core of the Earth is Earth's LayersIf you could cut the Earth in half, you could see that it's made of several different layers. The outermost layer, called the crust, is the one that we walk on every day. The layer beneath the crust is called the mantle....
Earth's core is structured in a solid inner core, mainly composed of iron, and a liquid outer core. The temperature at the inner core boundary is expected to be close to the melting point of iron at 330 gigapascal (GPa). Despite intensive experimental and theoretical efforts, there is lit...
