Sound waves have been used in the lab to mimic the role that gravity plays in driving convection in huge rotating bodies such as stars and planets. The new experiment was created by Seth Putterman and ...

In the early 2000s, some scientists developed models of heat-driven movement (convection) in the mantle that naturally gave rise to something that looked like plate tectonics on the surface.

Mantle Convection The core-mantle boundary (CMB) represents the lower boundary layer of the Earth's mantle and is structurally very complex with thermal plumes, thermochemical piles (LLSVPs) and ...

Many geophysicists believe that this cyclical pattern could be related to regular disruptions in the convection currents in the Earth’s mantle, upon which the continents float. However, scientists ...

Findings from a table-top experiment have revealed that the primary driver of a type of fluid flow called solutal convection has been overlooked. What's more, once this driver is accounted ...

Then we use the operator splitting method to perform time-stepping after space discretization. The resulting linear systems of equations are well conditioned and sparse, and by numerical experiments ...

Based on observations of the dynamics and microphysics of convection, the MIT scheme performed better than the often-employed idealization based on bulk-entraining plumes, but it tended to ...

Previously, researchers would make models of heat-driven convection in the mantle that matched observations of the real mantle pretty well, but didn't mimic the crust.
