Earth's Layers Exploration
Field notes
Earth has four main layers. The crust is the thin, solid-rock surface where we live. Beneath it is the very thick mantle, made of hot rock that is mostly solid but can slowly flow over long periods. The outer core is a liquid layer made mainly of iron and nickel. At the centre is a solid ball made mainly of iron and nickel. It stays solid because the pressure there is enormous. This central layer is the hottest layer.
