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 ...

A clear, exam-focused explanation of plate tectonics, continental drift and ocean basin evolution that is crucial for UPSC ...

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 ...

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 ...

New research reveals that Earth’s continents owe their stability to searing heat deep in the planet’s crust. At more than 900°C, radioactive elements shifted upward, cooling and strengthening the ...

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 ...

A new study of the chemical components of rocks led by researchers at Penn State and Columbia University provides the clearest evidence yet for how Earth's continents became and remained so stable — ...

Far beneath the waves of the southwest Pacific, scientists have finished charting a landmass so large and so coherent that it now stands beside Africa, Asia and the rest as a full-fledged continent.

Across the planet, water makes up 71% of Earth's surface. The remaining space is covered by land—continents and islands. Before Earth's land formed the seven continents in the present day, all the ...
