The earth is divided into three main layers:
· Inner core and outer core (core)
· Mantle
· Crust
1) Core:
The total radius of core is about 2100 miles. It has temperature upto 7200°C.
2) Mantle:
It is situated under the crust or surface of the earth and is divided into two parts:
-Upper Mantle
-Lower Mantle
3) Crust/surface of the earth:
Mainly it is composed of silicon, aluminium calcium, sodium etc.
The crust is thinner under the oceans (6-11 km)
where is continental crust are thick (25-90 km).
