What is the arrangement of earth's layers?

Answer 1

The earth has many layers. Deep inside, we first have the core which is divided into two parts the outer core and the inner core. Next is the mantle. Last of all, is the crust where we live.

Answer 2

The Earth consists of four main layers: the inner core, outer core, mantle, and crust. The inner core is solid and composed primarily of iron and nickel. The outer core is liquid and also made of iron and nickel. The mantle is semi-solid and rich in silicate minerals. The crust is the Earth's thin, outermost layer and is divided into oceanic and continental crust.
