Toward Core (internal)

Detailed explanation-1: -The solid inner core is situated about 3, 200 miles below the Earth’s crust and is separated from the semi-solid mantle by the liquid outer core, which allows the inner core to rotate at a different speed from the rotation of the Earth itself. With a radius of almost 2, 200 miles, Earth’s core is about the size of Mars.
Detailed explanation-2: -The outer core is the liquid largely iron layer of the earth that lies below the mantle. Geologists have confirmed that the outer core is liquid due to seismic surveys of Earth’s interior. The outer core is 2, 300 km thick and goes down to approximately 3, 400 km into the earth.
Detailed explanation-3: -The name “Bullen” or “Lehmann-Bullen discontinuity", after Keith Edward Bullen has been proposed, but its use seems to be rare. The rigidity of the inner core was confirmed in 1971.
