Continent formation on a pre-plate tectonic/young world
Hello! I have decided to do the masochistic thing and start a planet from scratch! The planet is now 1 billion years from birth so its plate tectonics would be initializing, but I'm wondering if there are means of continent formation without plate tectonics. (We also do not have many data points on this, so I also expect we just might not know at all and I can just go off of vibes.)
Would there be any continents at all, or would most land be below water? I'm imagining that the primordial volcanism and convection could be enough to make some elevation differences. Maybe those early continents would be more blobby and smooth since they're not formed by plates moving?
My thought process right now:
I used Orogen to initialize some plates, but the theoretical continents are harder since modern landmasses "hug" their plates due to being formed by them and certain rules apply, while ancient ones pre-date plate tectonics. But also since plates form based on weak points in the crust, continents will still follow some rules wrt new plates, since those would be thicker points in the crust? Maybe putting those continents more towards the middle of the plates and not crossing plate boundaries since plate convergences hasn't happened yet.
Thank you so much!
