Ancient rocks in Australia suggest Earth’s tectonic plates were already moving 3.5 billion years ago, reshaping understanding ...

Understanding lithospheric plate motions is of paramount importance to geodynamicists. Much effort is going into kinematic reconstructions featuring progressively finer temporal resolution. However, ...

Plates at subduction zones typically move just a few centimeters per year. But when accumulated stress at these convergent plate boundaries releases suddenly, the plates can slip several meters and ...

The desert floor in Ethiopia looks fixed and ancient, but it is moving. Across the Afar region and down the East African Rift ...

Renaissance polymath Leonardo da Vinci demonstrated frictional forces slow down the motion of surfaces in contact. Friction, he determined, is proportional to normal force. When two objects are ...

Mantle plumes—areas of unusually hot rock that can punch through the Earth’s crust to create volcanoes like the Hawaiian islands—have been thought to affect the motion of tectonic plates, but teasing ...

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 ...

The first direct evidence of how and when tectonic plates move into the deepest reaches of the Earth is published in Nature today. Scientists hope their description of how plates collide with one ...

Computational scientists and geophysicists have developed new computer algorithms that for the first time allow for the simultaneous modeling of Earth's mantle flow, large-scale tectonic plate motions ...

A team of researchers including Scripps Institution of Oceanography, UC San Diego geophysicist Dave Stegman has developed a new theory to explain the global motions of tectonic plates on the earth's ...

Earthquakes happen every day all over the world, along both tectonic plate edges and interiors. Earthquakes occur along faults, which are fractures between blocks of rock that allow the blocks to move ...
