The Lehmann discontinuity is a boundary within the Earth's interior that separates the outer core from the inner core. It is named after the German geophysicist Ernst Lehmann, who identified this transition in the early 20th century. The outer core is composed of molten iron and other elements, making it liquid, while the inner core is solid and consists primarily of iron and nickel.
