Which layer lies directly beneath the Earth's crust?

Explanation:
Directly beneath the Earth's crust lies the mantle. The crust forms the outer skin, and beneath it sits the thick layer of rock that makes up the mantle, separated from the crust by the boundary known as the Mohorovičić discontinuity. The atmosphere sits above the crust, while the outer core and inner core lie much deeper, beneath the mantle. The mantle’s upper part even includes the partially molten asthenosphere, whose flow helps drive plate tectonics.
