Yes, it is more viscous.
A portion of the upper mantle known as the asthenosphere.
the inner core
The lithosphere is defined as the crust plus the brittle, uppermost mantle to which it is attached. The part of the upper mantle called the asthenosphere is ductile, and is the portion of the mantle on which the lithosphere 'floats'. Essentially, it is a difference in the degree of ductility. The lithosphere is brittle; the mantle is ductile.
The asthenosphere.
The asthenosphere is made of soft rock and bends like plastic in the mantle.
the plasic like rock of the lower mantle is the asthenosphere

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...
