2. crust, mantel, or core
There are three layers of the Earth. The inner most is the core and it is the densest layer followed by mantle and the upper most layer is the crust. Crust is the least dense of all layers and is brittle in nature. Crust is a very thin layer on which we live. Mantle is thicker than crust and has silicate rocks with magnesium and iron. Outer mantle and core forms the lithosphere. The outer core contains Iron and nickel in molten form. The inner core also has iron and nickel. Inner core is solid.
