The record-breaking mission offers an unprecedented opportunity to study the geology of our planet’s largest layer.

When most of us think about what shaped our planet, we probably picture volcanoes, earthquakes, and huge continents slowly drifting apart (or back together again) over millions or billions of years.

The surface of our planet is a true geological theater where a permanent spectacle of movements and transformations takes place. These impressive phenomena result from plate tectonics, a ...

The Earth's mantle might not always move along in lockstep with the overlying tectonic crust—as set out in science textbooks for decades—but may instead behave differently. This is the conclusion of ...

The layer of molten rock corresponds with the upper mantle, also known as the asthenosphere. Illustration: cigdem (Shutterstock) Earthquakes and volcanic eruptions are a result of the movement of ...
