Globe

It is thought that the center of the earth is composed ofiron, nickel, and rock, making up the inner core (solid) and outer core (liquid). Above the core is the mantle, which comprises about 80% of the volume of the earth. The mantle is a thick liquid. Thevery outer layer is the crust, which is a layer of rock. Even at its thickest point, the crust is only 60 kilometers (37 miles) thick.
*Cut out the card above and save it. You can collect the cardsfrom each of the Papercraft projects to make your own mini-book!

Directions
Print out pages 1 through 7, cut out each individual part along their cut lines, and fold along the mountain and valleyfold lines.
