At the center of the Earth lies the core, which is nearly twice as dense as the mantle because its composition is metallic(iron-nickle alloy) rather than stony. Unlike the yolk of an egg, however, the Earth's core is actually made up of two distinct parts : a 2, 200-kilometer(1, 400-mile) thick liquid outer core and a 1, 250-kilometer(775-mile) thick solid inner core. 4, record 2, English, - Earth%26rsquo%3Bs%20core

In composition, the Earth is made of three nested spheres. At the center of Earth, a body of intensely hot iron and nickel forms the core. A less dense and much larger middle sphere is made of materials rich in iron, magnesium and calcium comprises the mantle. The outermost layer is a thin veneer of lighter rocks called the crust. 5, record 2, English, - Earth%26rsquo%3Bs%20core
