Perfect for fans of geology, this necklace shows the layers of the Earth to scale! Sci Chic's 3D printed Core of the Earth Necklace is a throw back to all of the cutaway pictures from science textbooks from middle school.
The layers of the Earth are the crust, upper mantle, lower mantle, outer core and inner core. The crust is the thinnest layer and is about 30 kilometers thick. Together the mantle layers are the thickest layer. The total thickness of the Earth is 6,401 kilometers. All of the different layers consist of a variety of materials.
