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 ...

Deep within Earth’s core, scientists are uncovering signs of a hidden structure that challenges long-standing models of the planet’s interior.

New research from Florida State University and Rice University is providing a better estimate of the amount of carbon in the Earth’s outer core, and the work suggests the core could be the planet’s ...

Earth cross section showing the classic distinction between crust, mantle and core. But new research shows Earth's structure is far more complicated and may change over time. Analyzing an unusual ...

Scientists have shown that Earth’s basic chemistry solidified within just three million years of the Solar System’s formation. Initially, the planet was barren and inhospitable, missing water and ...

Researchers have made a new discovery that changes our understanding of Earth's early geological history, challenging beliefs about how our continents formed and when plate tectonics began. A study ...

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 ...
