WitrynaAsthenosphere. Beneath the lithosphere is the asthenosphere.Tiny amounts of melted rock dispersed through the otherwise solid asthenosphere make the asthenosphere weak compared to the lithosphere. The weakness of the asthenosphere is important for plate tectonics because it deforms as fragments of lithosphere move around upon and … Witryna9 kwi 2024 · The mixed lithospheric mantle was further refertilized by asthenosphere-derived melt due to the continued upwelling of the asthenosphere. The continental orogens associated with subduction-collision processes have long been considered as important sites for the growth and transformation of Earth’s continents.
