The Tibetan Plateau, often called the "roof of the world," continues to baffle geologists and others curious about Earth’s ...

The mantle is about 1,800 miles (2,900 kilometers) thick and appears to be divided into two layers: the upper mantle and the lower mantle. The boundary between the two lies about 465 miles (750 ...

If you were to slice through it, you would see the Earth is divided into distinct layers. On top is the relatively thin crust where we live. Beneath that is the 2,900 km thick mantle layer.

This contrasted with readings collected from the upper mantle that looked as expected—damped waves due to hotter temperatures. Talavera-Soza likened the difference to going for a run in hot or ...

Nobody knew what they are, and whether they are only a temporary phenomenon, or if they have been sitting there for millions ...

Plate tectonics give Earth its mountains, earthquakes, continental drift and maybe even helped give rise to life itself. But do other planets in the solar system have them too?

To find out, the team used whole-Earth oscillation data from 104 past earthquakes to create a detailed 3D model of the upper ...

"Unlike the upper mantle, where we found exactly what we expected: it is hot, and the waves are damped. Just like when the weather is hot outside and you go for a run, you don't only slow down ...
