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.
Thanks to Julio Lacerda and Franz Anthony from Studio 252mya for their wonderful illustrations. You can find more of their work here: 252mya.com/
Special thanks to Judy Pu for answering our questions about Snowball Earth.
Produced in collaboration with PBS Digital Studios: ar-vids.com/u-pbsdigitalstudios

Request for Eons - would like to see a segment about the geologic age when Earth became inundated with iron - some call the 'rusting of the planet'. - Thanks!

Volcanoes erupt and spew ash which blocks the sun. Google this: "1816 year without a summer."

can you please also use the metric system, it broadens your material to the rest of the world and gives users of the imperial system reference and knowledge of the universal scale. There is no good reason to not use both scales.

There was a tectonic plate movement,in witch caused masses amounts of volcanoes to erupt,putting a lot heat as well,causing the earth to heat up,in the center of our planet,causing the cold to go down to the poles & flash freeze the poles,just like in Antarctica is today,with frozen Tsunamis waves over it & all the sort in the sky,blanket the earth & cooled it down,causing the ice age & when the sort,cleared enough,to let the sun shine though,it started melting the ice back,just like what there doing now,there spraying the sky's around the world,in as many countries as they can,it cools down the center of our planet & causes the heat,to go to the poles & melt the poles,

You have the question back to front. It should be - what has caused the sun to get brighter.

@45 ACP You seem to be about 6 years old. An adult actually says something when they speak. Perhaps you would care to point out where in the video they claimed that volcanoes are cold. Or are you going to keep playing kiddy games?

I wonder what the shape the continents will take in 250 million years. Is continental shift fast or slow? or a mix?

Honestly to find out the truth it needs Chemistry, Biology, Astrophysics and Geology to come together. It's the only way to find out the truth. Space events could easily trigger an ice age and were believed to do so million or so years ago. Also, the equator is funny. Because it's very mixed. Sure it's warm but you also got large tropics. And the hottest place on earth is California. Which is the worst place to put a huge city. With unrestricted growth. No wonder it gets forest fires it's been stealing it's water from the land for decades. it ran the underground water dry I believe. And is stealing water from ranchers up north. transporting it to the city. Then you got Las Vegas another desert city.... That sun idea makes sense. Because in a billion years today it will be 10% brighter. and will be able to boil our oceans. And some think that it may be able to split the molecular bonds of h20. And the Hydrogen will escape into space. Kinda interesting.

So can we just grind up a bunch of basalt and dump it into the ocean to sequester CO2 and undo climate change?

Man, if only those sponges had banded together to stop climate change before the glaciers melted and flooded everything. How ever could life survive with temperatures over 40F?
