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. WebThe Earth's crust is broken up into pieces called plates. These plates move due to convection currents in the mantle. Heat from the core makes magma in the mantle … midwest dental electric handpieceThe 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… midwest dental chippewa falls wi
