Summary:
Eons ago Earth experienced a wild transformation: it turned into a giant snowball. These massive glaciation events, where ice encased the planet from pole-to-pole, are fittingly named snowball Earth. There were at least two occurrences: one around 717 million and another some 645 million years ago.
