WebThe asthenosphere is the middle section of the mantle. The Earth’s asthenosphere is also made up of reasonably solid peridotites. About 99% of the asthenosphere is solid rock, and the other 1% is a molten-like magma state. The asthenosphere is hot, and that heat makes it mechanically weak compared to the lithosphere. Web15 jul. 2024 · The asthenosphere is one of the mechanical layers of the Earth. It rests between the lithosphere and the mesosphere within the mantle.
