Which layer lies between the mantle and the inner core?

Which layer lies between the mantle and the inner core?

• A. Crust
• B. Outer Core
• C. Mantle
• D. Inner Core

Answer: (D)

Understanding how Earth's layers are stacked helps answer this. Between the mantle and the inner core lies the outer core. From outside to inside, the sequence is crust, mantle, outer core, inner core. The mantle sits above the outer core, and the inner core is at the center, so the outer core is the layer that lies between them. The crust sits above the mantle, and the inner core is the central solid sphere surrounded by the outer core. The outer core is a liquid layer of iron and nickel, and its movement generates Earth’s magnetic field.
