Which layer lies between the earth's crust and its core?

Explanation:
The layer between the earth’s crust and its core is the mantle. It’s the thick, rocky zone that directly lies beneath the crust and extends down to the outer core. The mantle is the largest internal layer and is where convection occurs, driving plate tectonics and volcanic activity in the upper part. The lithosphere is a rigid outer shell that includes the crust plus the very top part of the mantle, so it isn’t the single layer lying between the crust and core. The core is the center, and “mantle keels” isn’t a standard geological layer. So the mantle is the correct, between-crust-and-core layer.
