For decades, scientists have proposed that the planet may once have been a "Snowball Earth," and new research suggests oceans could have churned underneath an ice-covered Earth, potentially helping to provide life with vital nutrients.

By the latest Proterozoic, some 560 million years ago, glaciers had three times covered the Earth perhaps even to its equator, creating what some have called "snowball Earth." The continents that came to dominate the next era – the Paleozoic – were already in position. And a strange new group of organisms called the Ediacaran fauna came to dominate the world's oceans.

Snowball Earth describes a theory that for millions of years the Earth was almost entirely or wholly covered in ice, stretching from the poles to the tropics.

The Snowball Earth hypothesis posits that the Earth's surface became entirely or nearly entirely frozen at least once, sometime earlier than 650 Mya (million years ago).

Underwater Volcanoes Played Key Role In Ending Snowball Earth

Researchers say explosive underwater volcanos may explain the end of the most severe ice age known on Earth and paved the way for life as we know it.

Around 720-640 million years ago, much of the Earth's surface was covered in ice during a glaciation that lasted millions of years. Explosive underwater volcanoes were a major feature of this 'Snowball Earth,' according to new research.
