The layers of the Earth by Isaac, Noah and Isabelle

The layers of the earth are crust, mantle, outer core, and the inner core.  The crust is what we live on and walk on.  The mantle is like a peanut butter sandwich because it has two layers of solid rock which is like the two pieces of bread, and it has a layer of heated rock flowing between them which is like the peanut butter.  It makes up 85% of the Earth's weight.  The outer core is 3,000 miles beneath the crust.  The inner core is very hot, somewhere between 9,000 and 13,000 degrees Farenheit.  It is a solid ball of iron and other minerals.  It was pretty neat to see all the layers of the earth.
