Plate Tectonics Explained The interior structure of Earth is chemically divided into an satellite solid crust, the pall, a liquid outer core, and a solid midland core. The core is largely calm of campaign, along with nickel and silicon. Other lighter elements are normally in the crust. The core is divided into two parts, the solid intimate core and the liquid outer core. The intimate core is idea to be solid and primarily made up of branding iron and some nickel. The outer core is all around the inner core and is believed to be made up of liquid iron mixed with liquid nickel. The outer core is about 2890 to 5100km. The inner core is 5100 to 6378km.
Earths mantelpiece is mainly composed of substances high in iron and magnesium. The melting point of every substance depends on the pressure and the deeper we go the higher the pressure becomes. Because of this the upper mantle is said to be semi-molten and the lower mantle solid. The upper mantle iron-substances are semi-molten because it is hot and they ...If you want to get a replete essay, order it on our website:
