Which layers makes out the Earth?
A
core, mantle, crust
B
inner and outer layers
C
atmosphere, hydrosphere, stratosphere
D
None of the above
Explanation: 

Detailed explanation-1: -Earth is divided into three main layers. The dense, hot inner core (yellow), the molten outer core (orange), the mantle (red), and the thin crust (brown), which supports all life in the known universe. The mantle is the mostly solid bulk of Earth’s interior.

Detailed explanation-2: -Unlike the mineral-rich crust and mantle, the core is made almost entirely of metal-specifically, iron and nickel. The shorthand used for the core’s iron-nickel alloys is simply the elements’ chemical symbols-NiFe. Elements that dissolve in iron, called siderophiles, are also found in the core.

Detailed explanation-3: -Earth’s layer’s names are: Crust: the outer layer of rock on which humans and animals live and plants grow. Mantle: a semi-solid magma layer consisting of iron, magnesium, and silicon. Core: centrally located solid mass of metal (inner core) and a liquid mass of iron and nickel (outer core).

Detailed explanation-4: -The structure of the earth is divided into four major components: the crust, the mantle, the outer core, and the inner core.
