How does the internal structures of earth's density compare to the lithosphere's density?
It is a lot greater, a little greater, a lot smaller or a little smaller?

The internal core density of the earth is about four times that of the lithosphere. That is a LOT. See
http://jersey.uoregon.edu/~mstrick/AskGeoMan/geoQuerry57.html for data on that.
