Answer:
Earth can be divided into three main layers: the core, the mantle and the crust. Each of these layers can be further divided into two parts: the inner and outer core, the upper and lower mantle and the continental and oceanic crust. Both the inner and outer core are made up of mostly iron and a little bit of nickel.
Answer:
The three layers of earth are: atmosphere, lithosphere, hydrosphere.
Explanation:
Atmosphere
It is the blanket of gases protecting the earth from harmful rays of sun which has severe attacks.
Atmosphere is further divided into:
1. Troposphere is situated at the 11 km above earth's surface. It has the temperature of -56°C. The total mass it contains is 96% of the earth.
2.Stratosphere is situated at the 11-80 km above the troposphere. It has the temperature of -40°C. The total mass it contains is 19.9% of the earth.
3.Mesosphere is situated at 25 km above stratosphere. It has the temperature of -96°C.
4.Thermosphere is situated at 95 km above mesosphere. It has the temperature of -1200°C.
5.Exosphere is topmost layer of the atmosphere.
Lithosphere
It is the total landmass of the earth where all the organisms lives. It is of about 20% of the whole earth.
Hydrosphere
It is the total water bodies of the earth where all the aquatic lives survives. It is of about 80% of the whole earth.
