(Phys.org) —A pair of Australian researchers studying rock samples has found evidence to suggest that the Earth's tectonic plate activity peaked approximately 1.1 billion years ago. In their paper published in the journal ...
By analyzing Mercury's rocky surface, scientists have been able to partially reconstruct the planet's history over billions of years. Now, drawing upon the chemical composition of rock features on the planet's surface, scientists ...
