Scientists think that Earth turned into a "snowball" at least twice in quick succession around 700 million years ago due to significant and rapid drops in the solar radiation reaching the planet's surface.
"Snowball Earth" is a hypothesis referring to periods in our planet's long history when almost its entire surface was covered in snow and ice. Scientists have proposed several different processes like volcanic eruptions that blocked out the sun's rays to explain how the Earth became a snowball.
