On the inside, Earth is basically all rocks. We get all of our metal resources from the inside. Nickel, Iron, Granite, and many other elements and metals that I could go on and on about. In this section you will learn about the 4 layers: Crust, Mantle, Inner Core, and Outer Core. You will also learn what they are made of, how hot they are, how deep they are and some interesting facts about each layer.
