5. What are the main differences between the lithosphere and the asthenosphere?
A) The lithosphere is solid while the asthenosphere is liquid
B) Both are solid, but the lithosphere is cool and rigid while the asthenosphere is hot enough to slowly flow and deform
C) The lithosphere is composed of rock while the asthenosphere is composed of iron
D) The lithosphere is liquid and the asthenosphere is solid

B) Both are solid, but the lithosphere is cool and rigid while the asthenosphere is hot enough to slowly flow and deform

Explanation:

Both are solid, but the lithosphere is cool and rigid while the asthenosphere is hot enough to slowly flow and deform.

Explanation: The LITHOSPHERE can be defined as the rigid mechanically dtrong, outer layer of the earth which is divided into twelve major plates.

The ASTHENOSPHERE is the zone of the earth upper mantle below the lithosphere.

The lithosphere is the brittle crust and uppermost mantle. The asthenosphere is a solid but it can flow, like toothpaste.
