We speak of the Earth as consisting of three main regions; the crust as the solid outermost part, the inner core at the very center and the mantle in between. Then we give the regions where they come together names and we also subdivide the three main regions and give the subdivisions names.
It is the lithosphere and the asthenosphere that are the parts of the surface moving when we talk of continental drift.
The lithosphere is outer portion of the Earth. It is composed of the oceanic and continental crust, along with the rigid upper mantle.
The asthenosphere is the plastic like upper mantle directly below the lithosphere where rock can move, bend, and deform without breaking. Below that, the mantle become more fluid and is the major part of the volume of the Earth.
The inner most part, the core, is only about 15% of the whole Earth.
The lithosphere is composed of the crust and upper mantle of the Earth that behave as elastic brittle solids under stress. The lithosphere extends from the Earth's surface to a depth of between 100 to 200 km.
The asthenosphere is that part of the Earth which is viscous and undergoes ductile deformation and convection on a geological time scale. It is part of the upper mantle and is approximately 600 km thick laying below the lithosphere at a depth of around 100 to 200 km and it's base is around 700 km deep.

The relationship between the lithosphere and the asthenosphere is that they both make up the earth's mantle. The asthenosphere lies right below the lithosphere.
the lithosphere is the outer most part of the earth including the crust and outer mantle and he asthenosphere is the lava in which the lithosphere floats on including the inner mantle
They both make up the Earth's mantle
the asthenosphere
asthenosphere
The lithosphere sits on top of the asthenosphere.
The differences and similarities between lithosphere and asthenosphere are as follows. Lithoshphere is made up of rigid rocks flowing above asthenosphere. Asthenosphere has rocks that are more plastic like because they can flow even tho they are still solid rock. The top part of asthenosphere is the same as the lower part of lithosphere, if the top part of asthenosphere cools it then becomes part of lithosphere. Lithosphere and asthenosphere are both made up of the upper part of the mantle on Earth but Lithosphere is also made up of the crust.
Lithosphere, Asthenosphere, Mesosphere
the asthenosphere
The asthenosphere is more dense than the lithosphere.
The mantle is the layer where asthenosphere and the lithosphere are located.
The lithosphere and asthenosphere are both entirely part of Earth.
The lithosphere is cold and brittle whereas the asthenosphere is hot and dense.
The layer containing the Lithosphere, Asthenosphere and Mesosphere is the Mantle. The Upper Mantle composes of the Lithosphere while the Lower Mantle composes the Asthenosphere.
asthenosphere
Tectonic plates are segments of the lithosphere. They float on top of the asthenosphere.

The large sections of the lithosphere that float on the asthenosphere are called tectonic plates
