New research deepens the understanding of Earth's crust by testing and ultimately eliminating one popular hypothesis about why continental crust is lower in iron and more oxidized compared to oceanic ...
Earth’s continental crust may have begun forming hundreds of millions of years earlier than previously thought, Yale scientists say — and the reason will be obvious to anyone who has ever baked a cake ...
Ancient, expansive tracts of continental crust called cratons have helped keep Earth's continents stable for billions of years, even as landmasses shift, mountains rise and oceans form. A new ...

An artistic reconstruction of Earth during the Hadean eon (~4.5 billion years ago). Intense volcanic activity, heat from accretion, and frequent impacts kept the young Earth in a molten state. This ...
In 1981, scientists discovered one of the thinnest portions of the Earth’s crust — a 1-mile (1.6 kilometers) thick, earthquake-prone spot under the Atlantic Ocean where the American and African ...
All around the world, from the Red Sea to the deep ocean ridges of the Atlantic, lurk more than a dozen geological misfits. These scraps of continental crust are found in the middle of oceans, ...
