The layers of the Earth from the surface to the center are arranged as the crust, mantle, and core. The crust is the surface layer, beneath which lies the thicker mantle, and the core forms the innermost layer.
The correct order of the layers of the Earth from the surface to the center is option A, start from the crust, which is the Earth's outermost layer that we live on. Beneath the crust is the mantle, a thicker and denser layer made of hot, semisolid rock. Beyond the mantle lies the innermost layer, the core. This can be split into two parts: the outer core, filled with liquid iron and nickel; and the inner core, composed mainly of iron and is solid due to incredibly high pressure.
