Earth’s story may have hardened into place almost as soon as the Solar System began. That is the striking claim in new ...

Ancient tectonic plates continue to reshape the Earth's interior and reveal a deep connection to its global dynamics ...

A layer only a few to a few dozen kilometers thick may be draped across the boundary between Earth’s core and mantle, and ...

A global seismic study has revealed that ancient tectonic slabs buried 1,800 miles below Earth's surface are still deforming the lowermost mantle near the core-mantle boundary. Using over 16 million ...

For decades, geologists labeled a billion-year stretch of Earth’s history—from 1.8 to 0.8 billion years ago—as the “Boring Billion.” They assumed not much occurred during the time: mountain building ...

Stromatolites might look like rocks. But they are living relics of ancient systems that thrived on Earth billions of years ...

Two new seismic studies suggest Earth's core is more complex than previously thought, revealing both a possible 'innermost inner core' and widespread ultralow velocity zones along the core-mantle ...

New Curtin University research has revealed how massive ancient glaciers acted like giant bulldozers, reshaping Earth's surface and paving the way for complex life to flourish. The key to unlocking ...

Millions of years before blue oceans and wandering continents, the Earth in its early days was a molten, tumultuous planet — a roiling mixture of rock and metal condensing within the nascent solar ...
