New findings from Colorado’s rock formations provide physical evidence supporting the Snowball Earth theory, which suggests Earth was once frozen entirely, down to the equator. This study offers insights into a key phase of climate and life evolution. Credit: SciTechDaily.com Evidence from Colorado suggests glaciers once covered Earth to the equator, supporting the Snowball Earth theory. This discovery provides insight into early climate shifts and the evolution of life. Geologists have discovered compelling evidence in Colorado that hundreds of millions of years ago, enormous glaciers blanketed Earth as far as the equator, turning the planet into an icicle drifting through...
