Description
Many of us have heard about the most recent supercontinent, which is called Pangea. But there is strong evidence for others with the earliest one now speculated to have formed in the Neoarchaean era about 2.7 billion years ago. So what makes us think they existed? And if they are real, how did they form and then break up?
David Evans is Professor of Earth and Planetary Sciences at Yale University. He is a true puzzle-master, piecing together all the available clues, especially those locked up in the magnetic fields imprinted into rocks when they formed, to trace the formation and subsequent break-up of supercontinents.
