Researchers used small zircon crystals to unlock information about magmas and plate tectonic activity in early Earth. The research provides chemical evidence that plate tectonics was most likely ...

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 ...

It's well known that earthquakes can rock fault-filled places like the U.S. West Coast. But why do earthquakes happen in the middle of tectonic plates? When you purchase through links on our site, we ...

Computer simulations suggest that a collision with another planetary object early in Earth’s history may have provided the heat to set off plate tectonics. By Lucas Joel Some 4.5 billion years ago, ...
