Subduction-induced mantle flow has a considerable geodynamic impact on Earth. It can deflect mantle plumes, transport geochemical signatures and produce upwellings that generate atypical intraplate volcanism. The mantle flow produced by slab rollover sub
The division of the earth’s surface into continents and oceans is a consequence of plate tectonics but a geological paradox exists at continent-ocean boundaries. Continental plate is thicker and lighter than oceanic plate, floating higher on the mantle asthenosphere, but it can rift apart by thin...
A plausible explanation for the enigmatic seismic wave velocities observed in ultra-low-velocity zones (ULVZs) is the process of iron enrichment from the core to the silicate mantle. However, traditional models based on diffusion of atoms and penetration of molten iron fail to account for the ...
so gravity forces it downwards, displacing what is hotter (and less dense) upward (This should not be confused withforced convection, which uses fans or other devices that are not practical to build on the scale of a planet). In the sun, most of the energy to drive this process comes...
