B. Label the layers in the structure of the Earth
The image shows a cross-section of the Earth with labeled lines pointing to different layers. Here are the labels for each layer:
1.
Outer Core (closest to the surface)
2.
Inner Core (center of the Earth)
3.
Mantle (layer surrounding the outer core)
4.
Crust (outermost layer)
So, the labels should be filled as follows:
- Top line:
Crust
- Second line:
Mantle
- Third line:
Outer Core
- Bottom line:
Inner Core

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