Which layer lies between the crust and the outer core?

Which layer lies between the crust and the outer core?

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

Answer: (B)

Earth's internal structure has distinct layers arranged from the surface inward. The crust is the thin, outer shell. Right beneath it lies the mantle, a thick layer of silicate rock that stretches down to the outer core. The boundary between the mantle and the outer core occurs around 2,900 kilometers below the surface. The mantle is divided into the upper and lower parts, with the upper mantle containing the asthenosphere, which is partly molten and helps plates move. Below the mantle sits the outer core, which is made of liquid iron and nickel, and beneath that is the solid inner core. So the layer between the crust and the outer core is the mantle.
