The layer of hot, solid material between the Earth's crust and core is the ...

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

Answer: (A)

The layer described is the mantle. It sits beneath the crust and above the core, forming the bulk of Earth’s interior. It’s extremely hot, yet rock stays solid overall, though parts of it—especially the upper mantle near the asthenosphere—can deform and flow very slowly. This flow drives plate tectonics on the surface. The outer core is below the mantle and is liquid, not solid, and the inner core is the solid sphere at Earth’s center. So the mantle fits the description perfectly.
