I am under the impression that's coal.

Oil is from sea life. Though I did read that in the 80s so entirely possible its nonsense.

Nah, coal is plant matter too.

Trees from before anything existed that could break down wood

Yeah, that's what I said!

I guess algae and bacteria are close to plants.

[–] [email protected] 3 points 3 months ago

Not really, especially in this science sub

[–] [email protected] 3 points 3 months ago (1 children)

How close? Like cousins or Alabama cousins?

[–] [email protected] 4 points 3 months ago

Louisiana cousins I believe.

Yes and no. They're both hydrocarbons.

Coal is organic matter from dry land, so typically plants.

Oil is from organic matter that fell to the ocean floor, so microbial life, algae and the like.

But both are from and end up as the same types of organic molecules. Carbon and hydrogen.

Wow ok that's cool.. so then every* oil well is in a place that historically was underwater?

[–] [email protected] 9 points 3 months ago (1 children)

Yes, specifically shallow seas that are so rich that they go anoxic. Without oxygen, the organisms don't break down and just accumulate.

Can Texas just go back to being a shallow anoxic sea?

Please?

Yes. A lot of such places are still below the seabed, hence off-shore oil-rigs.
