The part of the mantle below the lithosphere is called the Asthenosphere.

The Asthenosphere.
The uppermost layer of the mantle is called the lithosphere. It is a rigid outer layer that includes the crust and a small part of the upper mantle. The lithosphere is divided into tectonic plates that float on the semi-fluid asthenosphere below.
The rigid layer that includes the upper part of the mantle and the crust of the Earth is called the lithosphere. This layer is divided into several tectonic plates that float on top of the partially molten asthenosphere below. The lithosphere is responsible for the movement of tectonic plates and the formation of geological features on Earth.
The rigid layer that is the upper mantle and crust is called the lithosphere.
The asthenosphere is located in the upper mantle, just below the lithosphere. The lithosphere is the outermost layer of the Earth's crust that includes the rigid upper part of the mantle, while the asthenosphere is a semi-molten layer below the lithosphere that allows tectonic plates to move.
The crust and uppermost hard rocky mantle, together, is known as the lithosphere, which is above the plastic-like upper mantle area known as the asthenosphere.

Lithosphere
The upper level of the mantle is called the asthenosphere. It is a semi-fluid layer of the Earth's mantle located just below the lithosphere. The asthenosphere plays a key role in the movement of tectonic plates.
