There are over 100 volcanos on Antarctica
Active or dorment?
Active. Not immediately spewing lava, but they aren't done.
Also, there's warm liquid water lakes underneath parts of the antarctic ice as well. And they're caused by geothermal vents, not global warming
I like this fact and as a geologist I’m a little numb to facts about the Earth. At some level, all land on Earth has a volcanic origin by virtue of us having a molten core, a rigid mantle, and a crusty crust that seeps magma/lava. Time metamorphoses and sediments the rock in different ways. Antarctica just had the misfortune of migrating to the South Pole where millions of years of snow fall lead to its icy encapsulation.
The good news is it's all melting! Antarctica can be free!
