A recent study confirms a European rock formation that extends from Scotland to Ireland likely holds clues about what was once a "snowball Earth " The formation is made up of rock layers as thick as 1.1 kilometers ( 0.7 miles ) that date back to the Sturtian glaciation, which occurred between 662 to 720 million years ago .

Scientists believe that, at this time, Earth more or less resembled a snowball due to its climate.
