- Title
Comment on 'Will Earth's next supercontinent assemble through the closure of the Pacific Ocean?'.

- Abstract
Also, it appears that extroversion is inherently favored by the models because, starting from initial conditions, there are always already subduction zones in the external ocean, in order to disperse the continent, and it will be easier to maintain subduction zones rather than generate new ones. Accordingly, the authors basically make the assumption that the mantle is weaker than in the experiments, and the crust is not so much (or not at all) weaker, and that hence a thicker crust gives a stronger lithosphere. Besides, there are also other processes affecting lithospheric strength, one being that a hotter lithosphere is thermally weaker, another that a hotter temperature leads to more melting, and the residue in the mantle in this case can again lead to a stronger lithosphere.
