Question

he following question has two parts. First, answer Part A. Then, answer Part B.

Part A:

Scientists analyzed a layer of Earth and determined it was solid, magnetic, and very hot. Which layer of Earth did the scientists most likely analyze?


the crust


the mantle


the outer core


the inner core

Answer 1

Part A answer: the inner core.

Reason: the inner core is solid, extremely hot, and made mostly of iron (and nickel), which is associated with magnetism. (The planet’s magnetic field is generated by the convecting liquid outer core, but the inner core itself is solid and very hot.)

Part B: I don't see the question — please paste Part B and I'll answer it.
