Geologists from ETH Zurich and the California Institute of Technology studying the Earth's interior using seismic waves have ...

A new high-resolution computer model shows rocks that are colder, or have a different composition, in Earth's mantle where ...

The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways ...

"We don't know exactly what they are or what material is creating the patterns we have uncovered," researcher Thomas Schouten said.

Hidden deep beneath the Pacific Ocean, researchers have uncovered anomalies in the Earth’s mantle that defy existing ...

Plate tectonics is a theory that explains how Earth’s lithosphere—its upper mantle and crust—is split into sections called plates, which move. These movements create mountains, volcanoes and ...

This volcano is the highlight of a chain of underwater mountains known as the Juan de Fuca Ridge (center of above image).

Using high-resolution models to study the Earth's mantle, scientists have identified zones of rocks in the lower mantle layer that are colder, or ...

Much of this movement is caused by subduction zones which are "places where one tectonic plate sinks below another," a statement by the study authors said. Subduction zones are "characterized by ...

Understanding the inner workings of our planet has always been a fascinating challenge for scientists. Now, a team of ...

New research shows that three sites spread along an approximately 620-mile portion of today's Denali Fault were once a smaller united geologic feature indicative of the final joining of two land ...
