| Inner Core | (Solid, innermost layer)
|-------------------------|
```
-
Top layer (brown): Crust
-
Second layer (yellow): Mantle
-
Third layer (orange): Outer Core
-
Innermost layer (red): Inner Core

C. Draw a line to match each layer of the Earth to its description
1.
Continental crust
-
Match: The part of the Earth we live on
2.
Oceanic crust
-
Match: Layer directly under the oceans
3.
Mantle
-
Match: Where volcanic lava comes from
4.
Outer core
-
Match: Made of liquid iron and nickel
5.
Inner core
-
Match: Solid ball as hot as the surface of the sun
