Earth’s plate tectonics could be a passing phase. After simulating rock and heat flow throughout a planet’s lifetime, researchers have proposed that plate tectonics is just one stage of a planet’s ...

Earth is estimated to be 4.5 billion years old, but understanding when it evolved from a sizzling hot ball to a planet that could host life is a little more difficult. Earth is estimated to be 4.5 ...
