C

Explanation:We don't know what's in the core. It can't be atmosphere because you can't find minerals there. I also don't think it's mantle since that's right above the core and it's not being specific about what part.

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.
