The boundary between the asthenosphere and the lithosphere is normally below the Moho (which marks the boundary between the crust and the mantle).
The exception to this is below mid-ocean ridges where the moho and the lithosphere / asthenosphere boundary are at the same depth.
The layer directly below the lithosphere is the asthenosphere. The asthenosphere is partially molten and allows for the movement of tectonic plates above it.
The plastic-like layer below the lithosphere is called the asthenosphere. It is partially molten and allows the rigid lithosphere above it to move and drift on the flowing asthenosphere, causing tectonic plate movement.
The lithosphere lies above the asthenosphere. The asthenosphere is where isostatic adjustments take place and it is a very ductile region. Seismic waves pass slower through this region of the earth than they do through the overlying lithosphere.

The softer layer below the lithosphere is the asthenosphere. The asthenosphere begins at a depth of approximately 150 km. It has convection currents that arise from the heating and subsequent rising of material from the lower asthenosphere. These convection currents drive the movement of lithospheric plates at the surface, and are the cause of tectonic activity.
The layer directly below the lithosphere is the asthenosphere. The asthenosphere is partially molten and allows for the movement of tectonic plates above it.
I would draw the line at the base of the lithosphere, which is known as the lithosphere-asthenosphere boundary. This boundary separates the rigid lithosphere from the more plastic asthenosphere below it.
The lower boundary of the asthenosphere is not well defined. It lies below the lithosphere and above the lower mantle and outer core. It usually lies at depths of 80-200 km but can range as deep as 700 km.
I would draw the line at the base of the lithosphere, which is the boundary between the lithosphere and the asthenosphere. This boundary is characterized by a decrease in rigidity and an increase in ductility, marking the transition from the rigid lithosphere to the more plastic asthenosphere below.
Below the lithosphere is the asthenosphere, a semi-solid layer of the upper mantle. This layer is partially molten, allowing for the movement of tectonic plates above it. The asthenosphere is hotter and more ductile compared to the rigid lithosphere above.
You would draw the line at the base of the lithosphere, which is the boundary between the lithosphere and the asthenosphere. This boundary is located around 100-200 kilometers below the Earth's surface and marks the point where the rigid lithosphere transitions to the more ductile asthenosphere.
The plastic-like layer below the lithosphere is called the asthenosphere. It is partially molten and allows the rigid lithosphere above it to move and drift on the flowing asthenosphere, causing tectonic plate movement.
the Mesosphere
The lithosphere lies above the asthenosphere. The asthenosphere is where isostatic adjustments take place and it is a very ductile region. Seismic waves pass slower through this region of the earth than they do through the overlying lithosphere.
