Vidale, John E. Schubert, Gerald and Earle, Paul S. 2001. Unsuccessful initial search for a midmantle chemical boundary with seismic arrays. Geophysical Research ...

Geochemical observations appeared to support layering, whereas geophysical observations tended to support whole-mantle convection. The potential compositional boundary was typically put at 660 km ...

Three-dimensional disturbances exist on all scales from the molecular to those of the boundary conditions. In studies of mantle convection and other fluid problems in the Earth Sciences, the role of ...

Technological improvements over the past 15 years or so have allowed the acquisition of high-quality data for a whole suite of ... of the nature of mantle convection, degree of partial melting ...

but could never really be reconciled with the concept of mantle convection." "This model explains the observations in a simple way and permits a myriad of new hypotheses for global geochemical ...

"In this study, we perform whole‐mantle convection models to illustrate that strong mantle plumes can arise, weaken the lithosphere, and eventually initiate subduction [about] 200 million years ...

but could never really be reconciled with the concept of mantle convection.” “This model explains the observations in a simple way and permits a myriad of new hypotheses for global geochemical ...

Seismic tomography is a powerful tool to investigate the dynamic of the Earth's interior. In the last 10 years, the resolution of whole mantle seismic models has improved (Ritsema et al., 2011; Moulik ...

However, a convection oven includes a third heat source and a fan, which help distribute the heat throughout the oven.

Heat energy is conducted from the hot end of an object to the cold end. The atoms are fixed in place but are free to vibrate. When part of a solid absorbs heat energy the atoms vibrate faster and ...

It turns out that the vast oceans of hot plasma that make up the middle and outer layers of huge, geriatric stars churn much ...
