It is the asthenosphere. Because the lithosphere is a part of the crust and mantle. So that makes the asthenosphere underneath it because it is hard rock...
The Asthenosphere.
Tectonic plates are floating on the magma (semi-molten rocks) of the mantle layer. Therefore, they form the crust layer of the Earth.
The asthenosphere.
The mantle is the largest layer in the Earth's interior.
Its Is the mantle
The mantel made of partially molten rock which is commonly known as magma. The top layer of the mantle is usually hard.
Partially molten, plastic like, flowing layer located below the solid part of Earth's mantle is the Asthenosphere. The asthenosphere is mechanically weak and ductiley deforming region of the upper mantle.
The relatively soft layer of the upper mantle is called the asthenosphere
The outer core is the only molten layer of the Earth. == ==

Mantle.
The asthenosphere is partially molten; however, it is an interior layer which is separate from the Earth's inner and outer core. In fact, the asthenosphere is located directly under the lithosphere (the brittle outer shell of Earth), extending only a few hundred miles down from the surface.

The mantle is the hot rock.
