Continental clues: Modern continental rocks carry chemical signatures from the very start of our planet’s history, challenging current theories about plate tectonics. Researchers have made a new ...

What is the chemical composition of the Earth’s interior? Because it is impossible to drill more than about ten kilometres deep into the Earth, volcanic rocks formed by melting Earth’s deep interior ...

Earth’s surface environment hosts large reservoirs of hydrogen (H, mainly in the form of water, H2O), nitrogen (in atmospheric N2) and carbon (mainly in carbonate rocks). H, N and C are sometimes ...

A study published in Nature on April 2 upended conventional views about Earth’s earliest geological evolution. The research revealed that Earth’s first crust, formed about 4.5 billion years ago, ...

Scientists discovered how Earth recycles continents deep underground, shaping the unusual rocks found in ancient mountain ...

Our planet was born around 4.5 billion years ago. To understand this mind-bendingly long history, we need to study rocks and the minerals they are made of. The oldest rocks in Australia, which are ...

If you were to slice through it, you would see the Earth is divided into distinct layers. On top is the relatively thin crust where we live. Beneath that is the 2,900 km thick mantle layer. Then, ...

Scientists have uncovered new evidence that Earth's continents are continuously reworked deep beneath the surface, offering ...
