The rise of Earth’s continents may have tuned ancient oceans to just the right boron concentration for life to emerge, according to a new research study. (CREDIT: Wikimedia / CC BY-SA 4.0) Long before ...

Scientists recently published new ideas about why Earth’s toughest, oldest continents persist. These continents, known as cratons, have been on earth for more than two billion years. Andrew Zuza, an ...

Relative plate motions and plate boundary geometries are from Cao et al. (2024), with plate motions placed in a mantle reference frame. Continents are light grey, with continental margins shown in ...

For billions of years, Earth’s continents have stood firm, forming the foundation for mountains, rivers, and life itself. But what gave these massive slabs of rock their remarkable stability has long ...

Earth’s earliest continents may have set the chemical stage for life by regulating boron levels in ancient oceans, a new study in Terra Nova suggests. Scientists have long proposed that boron helps ...

An international team of researchers' analysis of minerals from the Pilbara region of Western Australia has given new insight into how ancient continents on Earth formed as far back as 3.5 billion ...

Researchers discovered that continents don’t just split at the surface—they also peel from below, feeding volcanic activity in the oceans. Simulations reveal that slow mantle waves strip continental ...

New isotopic evidence is rewriting the story of Earth's first continents. Imagine the planet nearly 3.8 billion years ago: a water world ringed by volcanic islands. How did solid continents arise in ...

The Arctic was not simply a cold edge of the Cretaceous world, but a place where mammals adapted, diversified, migrated and ...
