Web30 sep. 2024 · What is asthenosphere? The asthenosphere is the Earth’s layer beneath the lithosphere. It is a layer of solid rock in which extreme pressure and heat cause the rocks to glide like liquid. The asthenosphere’s rocks are not as dense as the lithosphere’s rocks and this low density allows for the lithosphere’s tectonic plates to move around on … Web11 apr. 2024 · South of the Nazca Ridge where the slab is subducting steeply, hot asthenosphere is present below the South American lithosphere 42.
