Web20 mrt. 2013 · The lithosphere–asthenosphere boundary (LAB) separates rigid oceanic plates from the underlying warm ductile asthenosphere. Web11 apr. 2024 · Numerical simulations suggested that edge-driven convection presumably occurred at a lithospheric step near the plume before the collision of the plume at the lithosphere–asthenosphere boundary (Duvernay et al., 2024); when a lithospheric step between the LT and HT2 zones was present, edge-driven convection would have … Web1 mrt. 2024 · The asthenosphere is the denser, weaker layer beneath the lithospheric mantle. It lies between about 100 kilometers (62 miles) and 410 kilometers (255 miles) beneath Earth’s surface. The temperature and pressure of the asthenosphere are so high that rocks soften and partly melt, becoming semi-molten. chipmunk\u0027s rr
