WebJul 23, 2024 · The lithosphere is the rigid outer layer of the Earth and is composed of rocks and minerals. It is made up of the entire crust as well as the upper part of the mantle . WebLithosphere consists of the crust and the upper mantle, and behaves like a hard layer that breaks and bends. Asthenosphere is warm enough to flow slowly. Why is the lithosphere rigid while the asthenosphere is not? The temperature in the asthenosphere is higher than the lithosphere so the rock is softer.
