 :Mid-ocean ridges can even be raised above the ocean surface--Iceland is actually the high point on one of them. In other places they're trenches, though.

 The current explanation seems to include water-thickness in with (either) air or ground thickness in discussing it in the initial transition from air to ground. Depends how you read it, which, but it easily reads as either. Maybe edit that aside out from that bit, then make sure that sliver of water is gone into later (...end of that para? ...footnote mention?) that sometimes the air ends at sea-level and ground starts after the depth of sea?

 The current explanations refers to fire as being 12000km, I would rather go with the radius of 6000km. Makes more sense to me since we are on a sphere and not counting the crust thickness twice.[[Special:Contributions/108.162.216.52|108.162.216.52]] 17:52, 18 December 2019 (UTC)
