Which layer lies between Earth's crust and core and is composed of hot, solid rock?

Explanation:
The layer between the crust and the core is the mantle. It is made of hot rock that behaves as a solid, though it can flow very slowly over long timescales. This gentle, plastic flow drives convection currents that move Earth's tectonic plates, which rest on top of it. The outer core is liquid iron-nickel, not solid rock, and lies below the mantle, while the inner core is a solid sphere at the center. The crust sits on top of the mantle. So, the described layer is the mantle.
