Geologists find evidence supporting Snowball Earth theory in ancient Colorado rocks

Geologists from the University of Colorado Boulder have found strong evidence supporting the "Snowball Earth" theory, which suggests that glaciers once covered the entire planet, including equatorial regions. This study, published in a scientific journal, focuses on ancient rocks in Colorado. The researchers used advanced dating techniques to show that these rocks were buried between 690 and 660 million years ago, likely due to heavy glaciers. This discovery indicates that ice sheets may have been several miles thick, transforming Earth into a frozen state. The findings suggest that the first multicellular organisms may have appeared in the oceans after this global freeze ended. The study enhances understanding of Earth's geological history and encourages further research into similar features across North America.
