The composition of the asthenosphere
WebEarth's mantle is divided into two major rheological layers: the rigid lithosphere comprising the uppermost mantle, and the more ductile asthenosphere, separated by the lithosphere … WebApr 6, 2024 · The lithospheric plates, like mosaics of the Earth’s surface, are moving coherently over the weaker, convecting asthenosphere. The lithospheric structure and thickness dictated by mantle dynamics play a first-order role in understanding the active tectonics and morphological evolution of the Asian region.

WebGeologists often refer to the asthenosphere as the jelly in between two pieces of bread: the lithosphere and mesosphere. The core is also subdivided into an inner and outer core. The outer core is liquid molten metal (and able to stop S-waves), while the inner core is solid. WebThis layered structure can be compared to that of a boiled egg. The crust, the outermost layer, is rigid and very thin compared with the other two. Beneath the oceans, the crust varies little in thickness, generally …
