Thus, sial (si-silica and al-alumina) is the name given to it. Sima (si-silica and ma-magnesium) refers to the silica and magnesium that make up the majority of the oceanic crust.
The mantle is located at a depth of 2900 km below the surface of the Earth. The core, which has a radius of roughly 3500 km, is the outermost layer. It is called nife (ni = nickel and fe = ferrous, i.e. iron) and is mostly composed of nickel and iron. The pressure and temperature in the central core are quite high.
