Basically the Earth is layered because of gravity. The earth formed in the molten state. The liquid iron which is very dense fell to the center. The rest of the earth is made up of silicate materials with SiO2 being the main component.

Remember the saying,
<em>"Give a man a fish and he will eat for a day, teach a man how to fish and he will eat forever"</em>
Well the Gopniks in Russia wrongly translated with saying to: teach a man how to become a fish and he will eat forever. So during the 1970-90s the gopniks all gathered near the lakes in order to satisfy their famine from communist regime. Unfortunately humans can not breathe under water so, fisherman in present day are still recovering bodies from the bottom of these lakes of these gopniks. Thousands still remain in lakes across this nation.
