Zoomable Art: The Earth, from Surface to Center
If we could break open the Earth, we would see that its interior consists of a series of concentric layers, called (in order from the surface to the center) the crust, the mantle, and the core. For more information, see the Section 2.7 What Are the Layers Made Of? starting on p. 47 and the Featured Painting on pp. 50-51 in your textbook.
