Snowball Earth Due to Plate Tectonics?

About 700 million years ago, the Earth is known to have undergone a period of climate change that sent the planet into a deep freeze. The freeze, lasting millions of years, is what geologists now refer to as the Snowball Earth period. Several theories have been proposed to explain what might have triggered this dramatic cool-down, which occurred during a geological era called the Neoproterozoic. A new study suggests that those major climate changes can be linked to one thing: the advent of plate tectonics.
