Earth part 2
Sorry i have not posted in a while, but anyway, we had some basic facts in part 1, well now I'll be talking about the underground of earth and many other things associated with that subject. So without further a do, lets go.
So the Earth has a mantle, which is split into two parts, the upper and the lower, which are 2,900km deep combined and normally 500 to 900 degrees Celsius. The temperature is around Then the crust, which we stand on and is about 70 kilometres deep, the temperature varies. next is the outer core which is liquid and 2,216km deep and is made out of iron and nickel, it is around 5000 degrees Celsius. The inner core is solid and is again, made out of iron and nickel and is 1,220 km deep and is around 5000 degrees Celsius. well that's it, here is a little diagram to help you. Bye peeps!
