describe the structure of the interior of the earth
Answers
Answer:
The 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. Beneath the Moho is the mantle, the viscous layer that makes up more than half of Earth's volume.

Answer : The Earth consists of three main concentric layers. These are called the crust, the mantle and the core of the earth. The crust consists mainly of two types of rocks - granite and basalt. The mantle of the earth lies below the crust and has an average thickness of 2,840 km. It consists of mixed silicates and metals (magnesium and iron) and is rich in olivine. The density of the Mantle itself varies between 3.0 gm/ cm3 and 5.5 gm/ cm3. The core is a compound of alloys of carbon, iron and silicon. It is found in molten stage. It consists mostly of metals. As nickel and iron are the two most abundant metals, the core is called Nife (Ni - nickel; Fe - iron). The density of the core is between 13 g/cm3 to 15 g/cm3.
