"Pumice is created when super-heated, highly pressurized rock is rapidly ejected from a volcano."
So what is pumice made of?
Solidified lava foam. It is full of holes because of the coming out of solution, and then expansion, of the gases that were previously dissolved in the magma under high pressure. Pumice does not exist until the pressure suddenly drops, as the liquid rock is expelled into the air during an eruption. Only at that point does the lava foam up, and then it cools and solidifies, leading to a spongy rock that is often light enough to float on water.
It's not "what" it's made of; it's "how" and "when" it's made. i.e. on the surface, after being expelled.
These are the magmatic gases I am talking about.
Yes we all know about those. But the point is you don't form pumice underground.
Antarctica may have remained in place due to the high geological activity during the formation of the continent. https://en.m.wikipedia.org/wiki/Geology_of_Antarctica
Yes, there are Ocean currents that rely on wind and temperature but they move things that float.
Olga, please ask Fermer05 how he does his quick translations.
Is it safe to assume you know as much about Antarctican geology as you know about the formation of pumice?
О.к., сейчас спрошу.
Can you tell me which translator you use to translate Russian texts?
Olga, greetings from Kizlyar, thank you for supporting a fellow countryman.
Дагестан? Здравствуйте! Я тоже рада увидеть здесь своего.
