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

The layer of the Earth located between the outer core and the crust is the mantle. The mantle is a significant portion of Earth's structure, comprising about 84% of its volume. It is situated directly beneath the crust, extending down to the outer core. The mantle is primarily composed of silicate rocks that are rich in iron and magnesium, and it plays a critical role in the movement of tectonic plates due to its semi-solid state, allowing for convection currents that drive plate tectonics.

In contrast, the crust is the outermost layer of the Earth and is not situated between the outer core and any other layer. The core, which is composed of the outer and inner core, is situated below the mantle. The lower mantle is a part of the mantle itself, specifically the deeper region of it, but the term "mantle" can refer to the entire layer, which includes both the upper and lower mantle.
