Abstract:
In addition, despite the higher gravities, super-Earths exhibit the same plate's pressure-temperature structure, because the increase in gravity is offset by the decrease in plate thickness. With the same plate structure, the deformation mechanisms that occur on Earth might well occur on more massive planets. We investigate two cases: a coulomb failure criterion and a constant yield stress. We find that in both cases, super-Earths have more favorable conditions to deform the plate and maintain subduction.
In summary, terrestrial super-Earths and Earth are very likely to have similar tectonics; and if water is present, they may have similar geochemical cycles. Planned space telescopes (such as JWST) may reveal atmospheric components indicative of a similar planetary environment.
