How Volcanoes Froze the Earth (Twice)

The video explores the Snowball Earth hypothesis, detailing two major glaciation events during the Cryogenian period. It discusses evidence like drop stones and carbonate rocks, and examines causes such as volcanic activity, the carbon cycle, and the breakup of Rodinia. The video also addresses how life survived under ice and the eventual thawing due to CO2 buildup. The narrative concludes with the emergence of diverse life forms in the Ediacaran period.
