The document describes the four main layers of the Earth: crust, mantle, outer core, and inner core. It provides details about the composition and characteristics of each layer. The crust is the outermost layer and has two parts: continental crust and oceanic crust. Below the crust is the mantle, which is hot and solid. The outer core is made of liquid iron and nickel, while the inner core is solid iron and nickel. The document also discusses minerals, rocks, and the three main types of rocks: igneous, sedimentary, and metamorphic.
