Ilovethose sites (for different reasons). But Google for Jobs is the only site to use for legit remote jobs. Why? Google’s got the AI muscle. It knows what you’re looking for. It scrapes jobs from all the other sites, and even from company pages. And boy does it deliver. How t...
lower mantleplumescomposition-dependent viscosityThe mobility of two Large Low Shear Velocity Provinces (LLSVPs), often hypothesized to be thermochemical piles with higher density in the Earth's lowermost mantle, is important for paleogeographic reconstructions and understanding the Earth's mantle dynamics...

The large magnitude of the dimensionless Rayleigh number(Ra ~108) for Earth's ~3 000 km thick mantle is considered evidence of whole mantle convection. However, the current formulation assumes behavior characteristic of gases and liquids and also assumes Cartesian geometry. Issues arising from ...
