Two diamonds formed 700 kilometers below the Earth's surface reveal a life-giving synchronicity between shifting continents ...

For decades, geologists labeled a billion-year stretch of Earth’s history—from 1.8 to 0.8 billion years ago—as the “Boring Billion.” They assumed not much occurred during the time: mountain building ...

For years, Mars has sat in an awkward middle ground, too geologically quiet to look like Earth. At the same time, it is too ...

Caltech researchers have developed a new method to study Earth's structure deep beneath the surface, at the boundary between Earth's brittle crust and the underlying mantle, a region called the ...

Ancient plate tectonics in the Archean period differs from modern plate tectonics in the Phanerozoic period because of the higher mantle temperatures inside the early Earth, the thicker basaltic crust ...

The earth's surface is made up of two types of crust: A lot of volcanic activity occurs in the 'ring of fire'. The 'ring of fire' is a group of volcanoes that are located along the plate margin of the ...

The asthenosphere concept dates from early studies of isostasy 1, bolstered by the existence of a seismic “low velocity zone or LVZ” 2 beneath what we now understand to be the lithosphere. The upper ...

Have tectonic plates changed speed over the last 3 billion years? The answer has far-reaching implications, as plate tectonics affected everything from the supply of vital nutrients for early life to ...

An artist's render of Mars. (Kevin M. Gill/Flickr/CC BY 2.0) For decades, our picture of Mars was of a dead desert world. Its ...

Earthquakes and volcanism occur as a result of plate tectonics. The movement of tectonic plates themselves is largely driven by the process known as subduction. The question of how new active ...
