The Earth is divided into four main layers - the crust, mantle, outer core, and inner core. The crust is the thin outer skin of the Earth, making up only 1% of its volume. Below the crust lies the mantle, which is the largest layer and divided into upper and lower sections. Within the Earth is the core, with the outer core being liquid iron and the inner core being incredibly hot solid metals.
