Scientists used satellite data to confirm that Earth's crust is "dripping" into the mantle beneath Turkey's Central Anatolian ...

A new analysis of rocks thought to be at least 2.5 billion years old helps clarify the chemical history of Earth's mantle -- the geologic layer beneath the planet's crust. The findings hone scientists ...

While Earth and Venus are approximately the same size, and both lose heat at about the same rate, the internal mechanisms that drive Earth’s geologic processes differ from its neighbor. It is these ...

The Mid-Atlantic Ridge in Iceland. This area is the boundary between the North American and Eurasian tectonic plates, which move apart ~ 2.5 cm/year. Subduction and the formation of continents, a ...

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 ...

Here’s what you’ll learn when you read this story: Mantle plumes are important geologic processes—they interact with plate tectonics, create rich mineral deposits, and even contribute to mass ...
