WebApr 11, 2024 · Slab rollback is a feasible model to explain the upwelling of the asthenosphere in Yurongguo. The young ocean slab with a slighter density was often subducted with a low angle in the early stage, while slab rollback occurred because of the increasing density after the subduction slab dehydration. Web22. explain the process of mantle convection. Answer: Mantle convection is the very slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface. The Earth's surface lithosphere rides atop the asthenosphere and the two form the components of the upper mantle. 23. bishops lodge motel narrandera

"The mechanical properties of the asthenosphere are widely attributed to the partial melting of the rock. It is likely that a small amount of melt is present through much of the asthenosphere, where it is stabilized by the traces of volatiles (water and carbon dioxide) present in the mantle rock. However, the likely amount of melt, not more than about 0.1% of the rock, seems inadequate to fully explain the existence of the asthenosphere. This is not enough melt to fully wet grain boun… " - Explain the asthenosphere

Webcrust, mantle, core. Name the physical layers of Earth in order. lithosphere, asthenosphere, mesosphere, outer core, inner core. Explain main details about each layer. Crust: The outermost solid layer of Earth is the crust. There are two types of crust: continental and oceanic. Both types of crust are made mostly of oxygen, silicon, and aluminum. WebAsthenosphere. Beneath the lithosphere is the asthenosphere.Tiny amounts of melted rock dispersed through the otherwise solid asthenosphere make the asthenosphere weak compared to the lithosphere. The weakness of the asthenosphere is important for plate tectonics because it deforms as fragments of lithosphere move around upon and through it.
