WebMay 16, 2024 · The second rotating flow (Figure 3 at 450 km) surrounds the southern boundary of the Juan de Fuca Plate, acrossing the slab window around 45°N and moving NE. These results support the previous hypothesis about toroidal-mode mantle flows driven by the fast rollback (30 mm/yr) of the Juan de Fuca and Gorda slabs (Zandt & … WebHeat flow is the movement of heat (energy) from the interior of Earth to the surface. The source of most heat comes from the cooling of the Earth’s core and the radioactive heat generation in the upper 20 to 40 km of the Earth’s crust. Radioactive heat generation is a product of crustal rocks containing high concentrations of the naturally ...
