Density lithosphere

WebApr 6, 2024 · The narrow low-velocity layer below the lithosphere lies beneath East and Southeast Asia and is bounded by subduction trenches and cratonic blocks, which provides seismic evidence for the low-viscosity asthenosphere that partially decouples plates from mantle flow beneath and allows plate tectonics to work above. WebMar 1, 2024 · Lithosphere. The lithosphere is the solid, outer part of Earth, extending to a depth of about 100 kilometers (62 miles). ... Some geologists think the increased density of rocks in the transition zone prevents subducted slabs from the lithosphere from falling further into the mantle.
