The convection cells below the tectonic plates of the Earth

The convection cells of the mantle are symmetric and stable, constantly affecting our surroundings for billions of years. The basics are so simple that words are not necessary. Just have a look at this sketch below:

Convection cells - basic two rolls

The Reykjanes Ridge is a good example, with a pair of convection cells underneath. These convection rolls extend over all the globe. The subject introduced here as the Convection Cell System of the Mantle is therefore based on a very simple precondition. How this section is then extended over the entire globe and all the relevant implications is of course a bigger piece to swallow 🙂
