Webasthenosphere, zone of Earth’s mantle lying beneath the lithosphere and believed to be much hotter and more fluid than the lithosphere. The asthenosphere extends from about 100 km (60 miles) to about 700 km (450 miles) below Earth’s surface. Heat from deep within Earth is thought to keep the asthenosphere malleable, lubricating the undersides of … Web30 okt. 2024 · We envision here the lithosphere as the outermost layer of the Earth that moves more or less coherently as tectonic plates, due to its stronger rheology, and higher viscosity in particular. Rheology relevant for lithosphere thickness may be influenced by thermal and compositional effects (e.g., Lee et al., 2005), and may change gradually with ... damon carey facebook
