The crust is a solid layer made of rock
The crust is the thinnest layer of the earth
The Crust is around 30 kilometres thick

11. The Mantle is the second most outer layer of
the earth.

12. The Mantle is the second most outer layer of
the earth.
The Mantle is a really thick liquid layer made
of molten Rock. The mantle is sometimes
called a plastic layer instead of liquid.

15. The mantle is next to the outer core.

16. The mantle is next to the outer core.
The heat from the outer core makes the part
of the mantle closest to the outer core be
hotter than the rest.

17. The part of the mantle that is hotter is
lighter, so it floats to the top and cools.

18. The part of the mantle that is hotter is
lighter, so it floats to the top and cools.
After it has cooled it sinks again because it is
heavier.

19. The part of the mantle that is hotter is
lighter, so it floats to the top and cools.
After it has cooled it sinks again because it is
heavier.
This makes currents in the mantle that move
the crust above around.

The Inner Core stays solid because there is so
much weight on it the little bits that make it
up have no room to move.
