Which layer of the Earth is located between the outer core and the crust?

The mantle is the layer of the Earth that is situated between the outer core and the crust. It extends from just below the crust to the outer core, making it a significant portion of the Earth's internal structure. The mantle is composed of solid rock, but it can flow slowly over geological time due to the heat and pressure it experiences. This layer is crucial for processes like plate tectonics, as the movement of the mantle affects the movement of the tectonic plates located in the crust above.

The crust is the outermost layer and does not lie between the outer core and the crust, while the lower mantle represents a deeper section of the mantle, being part of the broader mantle layer itself. The term "core" refers to the innermost layers of the Earth, which are situated beneath the outer core, making it irrelevant in the context of this question. Thus, the mantle is correctly identified as the layer that lies between the outer core and the crust.
