1 The Earth’s InteriorCrust (Lithosphere)MantleOuter CoreInner Core
2 Inner CoreThe deepest part of the earth (1512 miles deep) is a solid that contains both iron and nickel.It is because of this that the center of the earth is a magnet, a compass.It generates a magnetic field that protects the earth from flying out of orbit.
3 Outer CoreOutside of the inner core lays the outer core ( miles deep).This is much like the inner core with the exception that it is a liquid that contains sulphur and oxygen (which lowers the melting point).
4 MantleOccupying 1789 miles of the earth is the magma (iron and magnesium) that makes up the mantle.Upper and lowerIt is extremely hot!!goopy; very plastic-like. (upper mantle)Mostly solid (lower mantle)
5 Crust Also called lithosphere This is the top layer of the earth, which is basically hardened mantle (magma).It contains two segments, the oceanic and continental crusts.Note: this is the same crust, it just depends how thick it is to determine if it is part of the Oceanic or Continental Crust.
6 Crust…cont’dFor instance, if you drained all of the water from earth, then there would be one, giant Continental Crust.Likewise, if you flooded everything, you'd have one, giant Oceanic Crust.
