Not only in the Earth's mantle, in the atmosphere and in the outer layers of the Sun, but also in a chemical reactor, the exchange of heat may not be as effective as originally thought. There, because warm fluid rises and hence induces movement, the turbulent convection can be 100 billion times stronger than in the typical cooking pot. Hot fluids mix turbulently with warm fluids. As the temperature difference between the cold and warm sides increases, the heat transport increases...

Institute of Physics -- Physicists in the US have proven that wax is a perfect model of the ocean floors. Using a tub of wax, geophysicists at Cornell and Columbia have produced a predictive model of tectonic microplates "“ one of the most important and poorly understood features of plate tectonics "“ for the first time. This research is reported today in the New Journal of Physics (www.njp.org) published jointly by the Institute of Physics and the German Physical Society...
