Question

Which question could scientists answer to identify a similarity between the mantle and the outer core?

A.
How dense is the layer?


B.
What is the layer made of?


C.
How hot does the layer get?


D.
Does the material in the layer move?

Answer 1

To identify a similarity between the mantle and the outer core, scientists could answer the question:

**D. Does the material in the layer move?**

Both the mantle and the outer core exhibit movement; the mantle undergoes convection, while the outer core is in constant motion due to the flow of molten iron and nickel, which contributes to the Earth's magnetic field. This aspect of movement can highlight similarities between the two layers.
