Ancient plate tectonics in the Archean period differs from modern plate tectonics in the Phanerozoic period because of the higher mantle temperatures inside the early Earth, the thicker basaltic crust ...

Microscopic zircon crystals discovered in Western Australia suggest that Earth may have had continental crust as early as 4.4 billion years ago, millions of years earlier than previously thought. For ...

Earth's surface is a turbulent place. Mountains rise, continents merge and split, and earthquakes shake the ground. All of these processes result from plate tectonics, the movement of enormous chunks ...
