What are the 5 main layers of the earth Actually environmental science need it now please

Outer CoreThe Outer Core surrounds the Inner Core. It is mostly iron and nickel and it is around 2,200 km thick. It is around 5,000 to 14,000° F. It is the only layer that is liquid. There is lots of heat inside of the earth because of the pressure and the density.AsthenosphereThe Asthensosphere includes the upper mantle. It is estimated to be around 250 km thick. The upper part of the Asthensosphere is semi-solid. The soft rock in this layer flows around slowly.LithosphereThe Lithosphere is the part of the earth we live on. Itincludes the crust and the hard, upper mantle. It is made of tectonic plates that move around. It is 150 km thick.Inner CoreThe Inner Core is solid and very dense. It is 1,230 km thick. It is very hot. It is made of iron and nickel. It is between 9,000 and 13,000° F. The temperature is so high because of the density.Mesosphere/Lower MantleRocks in the Mesosphere move very slow. In the Mesosphere it is semi-liquid. It is around 2,550 km thick. The temperature at the bottom of the Lower Mantle can reach 7000° F. The Mesosphere is mostly made of magnesium, iron, silicon and oxygen.

Explanation:

Scientists understand much about Earth's structural layers

C) electrons encircling a nucleus with neutrons and protons
