    The outer core extends from 2,900 km to about 5,150 km beneath the Earth’s surface. It mainly consists of liquid iron and nickel. The motion within this layer generates the Earth’s magnetic field. The Inner Core. The inner core is the central part of the Earth. It extends from a depth of about 5,150 km to the Earth’s center at about 6,371 km.
