The Earth is composed of four main layers: the inner core, outer core, mantle, and crust. The inner core is a solid sphere primarily made of iron and nickel, surrounded by the liquid outer core. Above the outer core lies the mantle, a thick layer of semi-solid rock that flows slowly over time. The outermost layer, the crust, is a thin, solid shell where we live, consisting of continental and oceanic plates.
