During Earth’s early formation, the planet underwent a period of differentiation that allowed the heaviest elements to sink to the center and lighter ones to rise to the surface. Earth’s internal layering can be defined by this resulting chemical composition. The three main layers of Earth include the crust (1 percent of Earth’s volume), the mantle (84 percent), and the core (inner and outer combined, 15 percent). [1]
