Detailed explanation-1: -The lithosphere includes both the crust and the brittle upper portion of the mantle. The lithosphere is both the coolest and the most rigid of Earth’s layers.

Detailed explanation-2: -The asthenosphere is a part of the upper mantle just below the lithosphere that is involved in plate tectonic movement and isostatic adjustments.

Detailed explanation-3: -The mesosphere is beneath the asthenosphere. It encompasses the lower mantle, where material still flows but at a much slower rate than the asthenosphere. A layer of liquid iron and nickel (and other elements) beneath the mesosphere.

Detailed explanation-4: -Answer: Lithosphere is the solid crust or the hard top layer of the earth. It includes the crust and the uppermost mantle, which constitute the hard and rigid outer layer of the Earth.
