Structure Of The Earth – Notes
Interior of the Earth
The earth is made up of several different layers of material.
The outermost layer is the crust.
The crust is classified into:
- Oceanic crust that consists of sima
- Continental crust that consists of sial
- The next year is highly viscous and is called the mantle.
The mantle is the thickest layer and forms 83% of the volume of the earth.
The outer core is made of nickel and iron, and is called Nife.
