"Earth is the only known planet which has plate tectonics today. The constant
movement of these giant slabs of rock over the planet’s magma creates
continents – and may have even helped create life.
In a new paper published in
Nature today, colleagues and I reveal secrets of
Earth’s crust 4.5 billion years ago. In the process, we also provide a new way
to approach one of the biggest enduring scientific mysteries: when did plate
tectonics begin?"
