The Appalachians are a billion years, two supercontinents, and 4 orogenic periods old. They’ve been eroding since 200 million years before the Rockies formed. They are the same range as the Scottish highlands, Scandinavian Mountains, and Atlas Mountains. The caves predate bones.
It's so cute when people on the east coast talk about mountains

Those supercontinents grew apart, broke up, and moved on, and we should too.
I love learning about prehistoric supercontinents, but the existing research never tells me what I really want to know: Did the continents like each other? Did they fall in love? Was the breakup hard? Do they ever wish they’d stayed together? There’s no damn NARRATIVE in these Wikipedia entries

These continents just put on glasses and expect us to believe people don’t notice they’re supercontinents??

Also, ChatGPT is not "bad for the planet". A whole continent covered with a kilometer of basaltic lava is bad for the planet. A ten-mile rock coming in at 20 kilometers per second is bad for the planet. Supercontinents are bad for the planet.
Just saying.

Like most of us, Earth has a lot going on under the surface — even in what may have once seemed to be its most unassuming layer
Subterranean ‘supercontinents’ reveal intriguing new clues to what’s happening beneath Earth’s surface | CNN
Research on hidden structures deep within Earth’s mantle challenges theories about our planet’s middle layer and could transform our understanding of plate tectonics.

Last of all, the basis for the planet's tectonic history! This covers about 200 million years of continental drift, starting with the breakup of two Supercontinents, and was primarily achieved in Blender. This is my first time using my new process, described here: old.reddit.com/r/imaginarym...

Reading up on the supercontinents like Pangea. Some are noted as having formed "3 ga" ago. Ok, what's a "ga" in this context?

Do they travel far, or mostly stick around the same area? Do they return, after?

In my lifetime the Atlantic Ocean has grown 23' wider, the Pacific 23' narrower. Pangea is still breaking up.
Before there was a super continent Pangea, there were the super continents of Rodina and Columbia.

Don't worry though, the big ocean surrounding it will evaporate in another 750 million years or so, no matter where the pieces end up.
In that time there will be several more supercontinents.
