Asked by asiansupreme to Emma, Mike on 6 Jul 2012.
I was always taught that there were 5 layers to the Earth
Starting from the inside and working out…
1) Inner core
2) Outer core
4) Upper mantle
but I guess it depends on what you are counting as a layer. On the crust itself there are lots of different layers of rock – do they count as layers too?
