I was wondering about this over the last few days. I`m sure such worlds exist throughout the universe. Earth is ~70% water & ~30% land. So this hypothetical exoearth is ~70% land & ~30% water. You could just take a globe & reverse the land & oceans. While less than half the amount of water on Earth, that would still be alot of water. This exoearth would still have impressive large oceans. What about climate, temperature, weather, organisms & other factors? And plate tectonics. Would plate tectonics behave on this exoearth like Earth's except in regards to ocean positions as opposed to continental positions? For example: oceans on this exoearth would come together & be broken apart like continents on Earth. On this exoearth you'd have Panmare followed by Gondwanamare & Laurasiaoceanus, then by today 6 large oceans corresponding to the positions of Earth's continents. It would be an interesting world.
