Web15 de jun. de 2024 · If this deep water cycle between the mantle and the surface is in balance, Earth’s sea level remains stable. If not, our planet could exist as anything from a singular global ocean to a desiccated world. Earth’s habitability has benefited greatly from the fact that Earth’s sea levels have remained relatively stable over billions of years. WebFrom the geothermal gradient it is also obvious that the outer core/mantle boundary is a big insulater. Since these two are separate heat transfer from the outer core to the mantle is also mainly by conduction. For the mantle it is a story of both convection and conduction. I dont think the final answer is known here. As an extra note.

Earth's lithosphere, which constitutes the hard and rigid outer vertical layer of the Earth, includes the crust and the uppermost mantle. The lithosphere is underlain by the asthenosphere which is the weaker, hotter, and deeper part of the upper mantle. The lithosphere–asthenosphere boundary is defined by a difference in response to stress. The lithosphere remains rigid for very long pe…
