The plate tectonics that determine the shape of our continents may have originated from a huge impact billions of years ago. This huge collision with the Earth, thought to have occurred around 4.5 ...

Modern plate tectonics may have gotten under way as early as 3.2 billion years ago, about 400 million years earlier than scientists thought. That, in turn, suggests that the movement of large pieces ...
