What is the main difference between the lithosphere and asthenosphere?

Hint: The crust and upper mantle make up the lithosphere, which is the earth's rigid outer layer. The asthenosphere is the upper layer of the earth's mantle, below the lithosphere, where convection is assumed to occur due to low resistance to plastic flow.

Complete answer:
The Earth underneath us is divided into layers, much like the space above us, with the center being the innermost layer. The lithosphere, asthenosphere, mantle, outer core, and inner core are the layers. The lithosphere and asthenosphere are two layers that are often difficult to distinguish. It is, however, important to learn to distinguish between the two.



Note: Remember that lithosphere and asthenosphere are very different from each other. They are difficult to differentiate; therefore, they are often mistaken for each other. But the lithosphere consists of the crust and the mantle whereas the asthenosphere is the upper layer of the earth’s mantle.
