But if sodium does form insoluble rocks, why is there so much of it still in the oceans? And what about chloride?

- pjc50 3y ago> But if sodium does form insoluble rocks, why is there so much of it still in the oceans? There's more than enough to go round? (Feldspars in particular need aluminum, so once that's all bound up you aren't going to get more feldspar even if there is surplus sodium. Think of the sea as the leftovers in a non-stochiometric reaction.)
- mcv 3y agoMakes sense, but still, according to https://en.wikipedia.org/wiki/File:Elemental_abundances.svg https://en.wikipedia.org/wiki/File:Elemental_abundances.svg there's even more aluminum than sodium on earth.
- hoseja 3y agoBecause the insoluble rocks are igneous, not biologically created. No mollusk has a feldspar shell or something.
