Answer:
There would be 2 layers: lithosphere and asthenosphere
Explanation:
They contradict each other because the lithosphere consists of the crust as well as the portion of the upper mantle, which acts as a brittle, rigid solid. the asthenosphere is a partially molten upper mantle material that acts plastically and can flow.
Or you can think of it as:
The lithosphere is the brittle crust and uppermost mantle. The asthenosphere is a solid but it can flow, like toothpaste. The lithosphere rests on the asthenosphere.
