Study: Ice flowing of ancient glaciers may have shaped chemical changes in the ocean.
Minerals swept up on land by this “glacial broom” altered marine chemistry and infused oceans with nutrients.
This ancient period of deep freeze, known as the Neoproterozoic Era , or “ Snowball Earth ,” lasted from about 1 billion to 543 million years ago.
Studying Snowball Earth offers a window into our planet’s past, but also presents valuable insights into modern climate change.
Scientists say major glaciation events took place at least twice between 720 million and 635 million years ago .
By the end of the Neoproterozoic , major chemistry shifts were taking place in Earth ’s atmosphere and oceans.
Such changes could have infused nutrient cycles and provided emerging life with the boost it needed to evolve into more complex forms.
