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 ...

Disregard what you learned in geography class—Earth may not have seven continents after all. From the earliest of grades, schoolchildren around the world have memorized the same lineup: Africa, ...

The first continents on Earth formed between 3 and 2.5 billion years ago. Geologists studying the oldest rocks found on Earth believe that partial melting, fueled by the heat released during the decay ...

Forget what you learned in school—Earth might not have seven continents after all. From an early age, most of us are taught to recognize seven continents: Africa, Antarctica, Asia, Oceania, Europe, ...

Tulane University scientists, working with an international research team, have identified why some sections of the Earth’s crust remain stable while others fracture — a discovery that challenges long ...

Forget what you learnt in elementary school geography, Earth apparently doesn’t have seven continents after all. From a young age, we’re taught that the world is made up of Africa, Antarctica, Asia, ...
