Detailed explanation-1: -The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth’s structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below.

Detailed explanation-2: -The asthenosphere is the denser, weaker layer beneath the lithospheric mantle. It lies between about 100 kilometers (62 miles) and 410 kilometers (255 miles) beneath Earth’s surface. The temperature and pressure of the asthenosphere are so high that rocks soften and partly melt, becoming semi-molten.

Detailed explanation-3: -The asthenosphere is the upper portion of Mantle. It is the chief source of magma that finds its way to the surface during volcanic eruptions. The crust and the uppermost part of the mantle are called the lithosphere.

Detailed explanation-4: -The lithosphere rides on the asthenosphere. The asthenosphere is solid upper mantle material that is so hot that it behaves plastically and can flow. The lithosphere rides on the asthenosphere.

Detailed explanation-5: -The asthenosphere is a soft and fluid layer responsible for driving plate tectonics motion. Earth’s crust (lithosphere) is like a hard, rigid shell and sits on top of the asthenosphere. Then, it rides it like a conveyor belt transporting it slowly from one place to another.
