2. The Earth
Our beautiful planet.
The Earth.

3. The Geosphere
It includes all the features of the earth’s surface: continents, islands, the sea floor, and everything below the surface.
It is made of layers...

4. The Earth is your home. But…
What is it like inside?

5. Imagine the Earth was a watermelon.

6. Imagine you cut a slice out of it.

7. What would you find inside?

8. The Earth has got 3 layers.1 2 3

9. 1 . The first layer is the Crust.

10. The Crust is the layer you live on.

11. The Crust is between 8 and 65 km thick.
The crust is made of rock
rocks

12. There are two types of Crust..1 2

13. There are two types of Crust..
The continental Crust
The oceanic Crust

14. The crust
forms the continents.
Continental

15. The continental Crust is made of granite. granite We make staircases
with granite

16. The Crust
is the crust under the oceans.
Oceanic

17. The oceanic Crust is made of basalt. It’s solid, not liquid. basalt
We make sculptures
With basalt

18. 2. The second layer is the Mantle.

19. The Mantle forms about half of the Earth.
The Crust
The mantle
The core

20. The Mantle is 2900 km thick. 2900km heavier rock
The upper mantle is made of heavier rock
The lower mantle is
made of soft rock and is hot
toffee
like

21. The mantel is mainly made of rock.
silicate
We make rings
with silicates

22. 3. The third layer is the Core.

23. The Core is 5500ºC at the centre.

24. The outer core is liquid
The Core is 3480 km thick.
liquid
The outer core is liquid
3480km
The inner core is solid

25. The Core is mainly made of metal.
iron
nickel
We make doors
with iron
We make coins
with nickel

26. The crust and the upper mantle form the Lithosphere.
Upper mantel

27. Let’s make it simple !
Imagine the Crust is
your tortoise aquarium.

28. The continental Crust is the island where the tortoise rests when it doesn’t want to swim.
The oceanic Crust
The oceanic Crust is the floor under the water where you sometimes put the coloured sand.
