volcanoes shooting stuff into space? I'd suggest you try that thread again on /b/ or something

>>9528849
Are you suggesting at no point in the history of Earth has a volcano had the force to shoot debris into space?

Maybe it is you who should go back to /b/.

That's not even the key point of focus in my post. Nice side step retard.

>>9528856
Feel free to educate me, it'd be greatly appreciated. I think if you find a source describing how a volcano shot stuff into space it will likely contain the correct term for this crazy phenomenon, so we both win today!

meteorite is something that falls down on earth from space, no matter where it originated
meteoroid, now that's another story
volcanoes aside, we had to shoot up a metric assload of those back when the moon was created
some of them may be still hanging in the neigborhood (aside from the moon itself)

>>9528874
Earth did not shoot up the moon into the sky. Most likely some big thing hit some other big thing and the result was earth and moon

>>9528889
that doesn't really sound like it would create two big spheres 400,000km from each other
the distribution of material doesn't make sense

>>9528902
You'd be surprised how many things don't really sound like they actually are. Would you guess that the lightning in a thunderstorm is actually an electric discharge created by differences in charges in the air even though it sounds more like a god smashing his rod down onto earth?

to be less condescending, check out the giant impact hypothesis, which is the currently most supported hypothesis on the creation of the moon

>>9528913
The irony in your post is palpable.

Not 10 posts ago you claimed no volcano in the history of Earth has been strong enough to shoot debris into space even though it is consensus that literally every other planet shoots debris into space when powerful volcanoes erupt.

>>9528924
some fucking few tiny moons in our solar system might do it because they are small and vile but that's it. I'm sorry I'm new around here I should lurk more I don't get this place

>what is krakatoa?

>>9528955
I gave two hypothetical examples as ways debris from Earth could end up in space, possible or not if you want to linger on an aside in my post that is your choice.

>>9528993
What isn't nowadays?

>>9528998

Just kidding. Your OP question is interesting.

>>9528921
what the fuck that's exactly what I meant, what did you take from it?
the earth farted moon out?

Meteors which come from Mars and the Moon aren't lofted by volcanos, They're "secondary meteorites", blasted into space by a primary impact.
A monster impact, like the one which erased the dinosaurs, could hurl fragments into space. Most of it came down again on Earth and started fires all over the planet. I guess a tiny percentage might have made it out of atmosphere with still enough energy to leave our gravity well.

Since it would have the same isotopic composition of the Earth, I'm not sure how we'd identify anything we dug up as having "come home". I doubt there's a specific name for them. Certainly not mentioned in any books on meteorites I've read.

>>9528924
How do you know it's the same anon?

>>9529182
Only two people post on /sci/, and since I am one of them.

But not Earth.

We call em artificial satellites, usually name them too

They were caused by the biggest, ongoing and growing cataclysm in the local universe: humanity

Unless there's a new theory since last time I looked, glassy meteorites formed from huge impacts into Earth that then fall back to the planet are called tektites. That would not cover every Earth-origin meteorite, I suppose.

>hurr durr humans are evil, leave earth to the animals
you should be launched into space with the other artificial satellites

>>9528817
Tektites
https://en.wikipedia.org/wiki/Tektite
>>For example debris fired into space by volcanoes
we call that pretty speculative. There is some evidence that volcanoes could launch ejecta at up to speeds of 2 km/s, which might be enough to go suborbital
