Also cool that for a period of like 60 million years, nothing decomposed dead trees. As they would die or fall over, they'd just stay there, piling up. This is where most oil came from. The massive amounts of trees stacking up before bacteria and fungus evolved to decomposed them. Imagine 60 million years worth of trees just lying around.

*Thought I'd add an edit, since this post got quite a few eyes on it: It was mostly coal that all those trees turned into. Not oil.

Didn't those trees become coal, not oil?

[-] ColeSloth@discuss.tchncs.de 8 points 1 year ago

Yes. I made mention of this in a reply to someone else as well. I'm not sure if my teacher (like 30 years ago) told us wrong or if I simply remembered it wrong.

I think near water they became oil and far from water they became coal

[-] RunawayFixer@lemmy.world 56 points 1 year ago

No, most coal comes from plants in swamps, because the water helped preserve the organic matter.

Plants in swamps die -> organic matter on the bottom of the swamp -> peat -> brown coal -> black coal.

Oil apparently comes mostly from plankton.

Oil was effectively plankton and other sea stuff.

Coal was forests.

Brother I finally found you.

We come from the same place you and me. Remember that barn?

[-] turtlesareneat@discuss.online 29 points 1 year ago

Mushrooms are the great undertaker, the great decomposer. The Langoliers. They are just waiting to eat you, and they're happy to share their fruits in the meantime. They're fattening you up. They can wait.

[-] voracread@lemmy.world 3 points 1 year ago

That Langoliers reference spotted in the wild!

I remember a flimsy tv film with even flimsier CGI spherical creatures eating the planet

[-] infinitesunrise@slrpnk.net 1 points 1 year ago

I was struggling to explain the plot of this one to my gf just the other day. Had to pull out screenshots of the TV movie to make it make sense.

[-] stabby_cicada@slrpnk.net 24 points 1 year ago

I imagine dead trees were flammable, even back then. And oxygen levels were 15% higher. Can you imagine the forest fires?

[-] Crassus@feddit.nl 21 points 1 year ago

Fire wasn't invented back then

[-] smeenz@lemmy.nz 7 points 1 year ago

And after it was invented, it was only in black and white until the 1950s

[-] ravenaspiring@sh.itjust.works 13 points 1 year ago

I love this fact, and am curious where you learned it?

[-] ColeSloth@discuss.tchncs.de 40 points 1 year ago

I learned it nearly 30 years ago in school. I just did a search and found a link about it, though.

Also, seems that either I remembered wrongly, or my teacher made a mistake, but it seems it was most of the worlds coal; not oil, that came from all the piles of trees from that period.

Correct. In theory, we could make more oil in the lab. We cannot make more coal, because the wood will get broken down by bacteria far before it turns to peat, lignite, sub-bituminous, or bituminous coal, and much less anthracite.

If you are here asking: "Is this a science meme?"

Probably, yes. We use the Dawkins definition of meme: a replicating idea, not just an image macro with a fact on it. A good post here doesn't need to teach you something. It needs to make you ask something: who, what, where, when, and especially why or how.

Science isn't a filing cabinet of facts, it's a conversation. For example, a photo of an eel or other localized wildlife counts because most people never see one, and wonder is the first step of inquiry. A car meme counts if it makes you curious about what's under the bonnet. If you want to talk about something you noticed in the world, chances are someone else wants to talk about it too.

We moderate for vibe, not category. Pruning is light, especially where a post creates interesting discussion. Experimenting is encouraged, but keep it in good faith and never punch down.
