Did the whole earth resemble Antarctica during the Ice Age, or the age of Snowball Earth? How did life survive?
I'm curious about the Ice Age and Snowball Earth. Did the whole earth resemble Antarctica during those times?
During the Snowball Earth period, which occurred about 635 million years ago, the Earth was completely covered in ice and snow from pole to pole. But during the Ice Age, which occurred much later, about 2.6 million years ago, only about a third of the Earth was covered by ice.
