Is the asthenosphere warm
WitrynaThe asthenosphere is thought to be composed of hot, viscous mantle rock. The word “asthenosphere” comes from the Greek words for “weak” and “sphere.” The name reflects the fact that this layer of the mantle is weaker than the layers above and below it. The asthenosphere is the layer of Earth’s mantle below the lithosphere. Witryna27 wrz 2024 · The lithosphere is the solid, outer part of Earth.
