>>362504>lifeless planet in a time of fire and toxic airThat's so wrong I don't even know what to say.
Appalachians came from the Alleghenian orogeny only like ~300 million years ago during the Permian period. The Earth was absolutely teeming with life at that point, and the atmosphere was more or less the same as today, plenty of oxygen thanks to all the fucking gigantic forests covering the planet which eventually became the coal found throughout Appalachia.
>tfw where the fuck did the coal come from on a lifeless planet? Why is it oftentimes found in the shape of trees?Well technically that's all from the carboniferous, predating the Appalachians, but whatever only a few tens of millions of years difference, which ain't shit over the 4.7 billion life of our planet.
