12.
Which explanation provides the best scientific reason for the ordered arrangement of Earth’s layers?
a)
Iron is magnetic, so the iron in the core binds together and is unable to move to other layers of Earth.
b)
The densest elements sink toward the center of Earth, while the least dense elements rise toward the surface of Earth.
c)
Some layers of Earth are solid, while others are liquid; therefore, they do not mix or move easily.
