Heya, I’m new in town. I was wondering if anyone here would give me some info about how a new Pangea would function (weather, biomes, etc). All the grand-scale worldbuilding tips I’ve came across so far have been based on earth-like planets, and not for one megacontinent. For the record, the image belongs the model I’m basing it off of.
And via Google we received: Any advice on building a new Pangea? The setting I’m working on takes place on a Pangea-esque mega-continent, and a lot of the advice about building the natural aspects of a world (biomes, weather, etc) since a lot of the advice I’ve been finding has been based on more earth-like worlds.
Tex: Supercontinents like Pangaea are not unique, and Earth is suspected to have undergone several periods of supercontinent formation and dissolution (Wikipedia), but the one you describe is currently the best-modelled one from reconstructions. Like any other large continent, weather patterns will follow basic patterns of distance from an ocean or sea, wind directions, and the ratio of deserts to temperate and tropical areas.
Life on Pangaea would have been diverse and with a wide geographic spread (Wikipedia), due to the lack of oceanic barriers. One consequence of this is that when there is an extinction event, it is comparatively much worse because there are many more members of a species to die off, which would affect the climate via destabilization of the trophic levels.
Supercontinents are capable of existing because of their definition in comparison to oceans. On arid planets, there would not be enough water to justify the boundaries of a continent, merely varying elevation levels. On oceanic or frozen planets, there is the same issue. Thus, Earth-like planets are a suitable shorthand for the description of something like Pangaea existing.
