Which layer lies between the crust and the core?

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

Answer: (A)

The layer between the crust and the core is the mantle. The Earth’s structure is crust on top, then the mantle, and beneath that lies the core (which has an outer liquid layer and an inner solid sphere). The crust sits directly above the mantle, and the mantle extends down to the boundary where the outer core begins. The mantle is a thick, hot layer of rock that can flow slowly, and it’s divided into upper and lower parts, with the upper portion including the asthenosphere that helps drive plate motion. The outer core and inner core are deep below the mantle, and the crust is the outermost shell above it.
