How Volcanoes Froze the Earth (Twice)

  • Over 600 million years ago, sheets of ice coated our planet on both land and sea. How did this happen? And most importantly for us, why did the planet eventually thaw again? The evidence for Snowball Earth is written on every continent today.

    CO2 isn’t strong enough to cause that big a shift. Maybe a couple of degrees, but the shifts involved are way to powerful to be driven by a minor shift like that.

    i would like to state that while some rocks can and do absorb CO2, most of the CO2 in the atmosphere is cleaned out by rain, and with 99% of all water on earth locked up in or below the ice, there was very little rain to clean the gases out of the atmosphere.

    Okay I don't believe in snow earth. Yes all continents was cover in snow but not all earth. The continentals that time were all together so its possible all of them were covered in snow but not all earth first because once its covered all in snow it's really hard to unfreeze because the reflecting of the snow and even with volcanoes you need thousands of them to melt the ice or to warn the earth than you came to the problem of global warming like venus if there to much co2 or methane in the air so that's why I don't believe in snow earth

    Is it possible that icy worlds such as the moons of some planets like Titan and Europa for example, are currently in their own Ice Age(s) and will eventually get to the point Earth is now?

    Wow, if I had a nickel for every time the Earth completely froze over, I'd have two nickels - which isn't a lot, but it's weird that it happened twice.

    You forgot to mention when did the sun returned from the 7% cooler output to warmer output.

  • Tegwyn Foster
    Tegwyn Foster 17 days ago

    The answer does not reside in Volcanoes. The answer is found in Plate Tectonics of which Volcanoes are a symptom. Continental drift along with orbital mechanics coupled with precession of the axis and solar output combined in a way to cool the planet. Carbon is not the regulator unto it’s self. The cryogenian period was ended when the continents formed.

    Maybe life flourished under the thick ice by getting energy from underwater volcanoes (which some aquatic species still do on Earth, and that theory also supports that there might be life under the ice on Jupiter's moon, Europa.

  • Jocelyn Brisebois
    Jocelyn Brisebois 19 days ago

    Scientists claim that air pollution dropped from the sky at the end of the inter-glacial period for some unknown reason, and at the other end, some scientists claim that mammoths froze as if they were falling into a cryogenic bath. so should it be possible that at the end of the inter-glacial period, for a temperature drop reason, the air liquefies until the space touches the earth for a certain time ???

    I watched this because I wanted to know if we can use some of this science to reverse the global heating effect we are experiencing. Its interesting that the runaway cooling feedback loop is the same (but the opposite) as the runaway heating loop we seem to have kicked off now.

    How does sulfur dioxide freeze the 18 million years later???? I understand it took a long time to rain out, but 18 million years?????? Isn't it more likely the shape of Rodinia blocking ocean currents was involved also?

    This is the answer to global warming, we just need a calculated ice age. A lot of people will die which helps solve the overpopulation problem while simultaneously helping with the overall amount of human pollution.

    The Earth froze over due to the time it took to exchange orbit with other stars. The Earth did not always orbit the Sun. Here is a video that explains how planets evolve: ruclip.com/video/CM0Hi0YwAJA/video.html

    How does weathering store c02?

    • Richard Trischka
      Richard Trischka 26 days ago

      well the co2 bounds with the rainwater over time and so turns it into a weak carbonic acid.....that carbonic acid rains down and instead of just disolving and releasing the Co2 again it it reacts with for example limestone,(what is basicly just calcium carbonate ) and so bounds the co2 in form of calcium bicarbonate.

      This process is called Chemical Weathering. But its a very slow process...

    Fantastic documentary! one question - Is it possible that another ice ball earth to happen in future? Or, the earth is going to get so warm in future that an ice ball earth or even an ice age can never occur?

    • John DC

      Probably not, since the formation of a supercontinent and the increase of the sun's luminosity in the future will just raise global temperatures gradually.

    Why is all I can think of during this video is
    "Super-heated rocks from the Earth's core is surging to the crust, melting ice built up over thousands of years." 🙃🙃🙃
    Also
    Evidence: the equator froze
    Scientists: no no no can't be... the Earth must've freaking flipped completely on its side

  • Fishslap 33
    Fishslap 33 Month ago

    I would like to point out here that liquid water at earth's pressure levels can't really get much below 0C regardless,. So for sea life at least, conditions wouldn't have changed too much temperature wise. Arctic waters now were at basically the same temperature as sea water would have been then. And the ice that forms on the surface insulates the water below, which helps it stay liquid. Dark and low on oxygen, yes. Also slightly less water to live in, since a lot of it is ice. But other than that, not so different.

  • Not Human

    Single cause theories are weak.
    More likely its was oxygen at high atmospheric levels, boom in life increased while decreasing carbon recyclers, earth either tilted or was hit hard enough by a commet to push it off its obrit, decreasing sunlight and temperatures starting a die off, more and more creatures died and killed most of carbon recyclers left, this run away reaction caused the earth to rapidly cool.
    It ended when oxygen couldn't be replaced, volcanic activity caused a melt somewhere and exposed large amounts of carbon mats, bacteria returned to eat it releasing more carbon then reversed it.
    Or life learned to survive off the deep seas with no where else to go and built up enough methane over time to be released.
    Life has away to survive if carbon, water, and some source of food to be tapped then piggybacks off of it to expand and adapt.

    But your whole assumption is that if life is here now, it must have lasted through snowball earth. That simply highlights that you do not know, nor accept that "life" can "start" somewhere. So please let me help. The earth itself can start. We believe it formed from star dust from another exploding star that (dust) was revolving around the sun. And a given form of "life" (e.g. prokaryotes) too can start. And it will start again in an infinite number of places. That is all common sense. But the key, that is missing here, is that "life" is not what you think it is, well, it is much more. In its greater definition, it actually has no "start" only evolution (no quotes, evolution is a very correct idea about life). Minerals precipitating is also life. Crystals growing is life. And there are natural logical subsequent steps, from there, leading to, RNA growing, etc... Just like some 8 billion years ago, the earth started growing, it is also alive. Then of course conversely "death" is also not that absolute end that it is defined as...
