The researchers theorize that these far-off remnants could either be deposits of silica-rich material that have hung around ...

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 ...

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

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

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

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 ...

An international team of geophysicists says it has discovered evidence of a "lost world" hidden beneath the Western Pacific ...

The plates are constantly sliding past, colliding into, or moving above or below each other. This movement results in ... Mariana Trench formed when one tectonic place was pushed under another.

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 ...

Geophysicists at ETH Zurich are using models of the lower mantle to identify areas where earthquake waves behave differently ...

New York, Oct 27 (IANS) Venus, known as a scorching wasteland of a planet, may have once had tectonic plate movements similar to those believed to have occurred on early Earth, found a study ...
