Carbon released from Earth's spreading tectonic plates, not volcanoes, may have triggered major transitions between ancient ...

Memorizing seven continents feels settled, like learning the alphabet. A new study argues the ground rules are less tidy.

From time to time, when Earth's tectonic plates shift, the planet emits a long, slow belch of carbon dioxide. In a new modeling study published in Geochemistry, Geophysics, Geosystems, R. Dietmar ...

Scientists have traditionally focused on volcanic arcs as the main natural source of atmospheric carbon dioxide. These form ...

A research duo from The University of Texas at Austin and UT Dallas have put forward a hypothesis that links the dawn of plate tectonics with "snowball Earth"--a period of climate change that sent the ...

A hidden chunk of an ancient tectonic plate is stuck to the Pacific Ocean floor and sliding under North America, complicating ...

Earth has six continents not seven, radical study claims ...

A handful of ancient zircon crystals found in South Africa hold the oldest evidence of subduction, a key element of plate tectonics, according to a new study published today in AGU Advances, AGU’s ...

Jupiter’s moon Europa features a warm subterranean ocean covered in ice. For years, scientists have wondered if certain surface features are the result of plate tectonics, which, if true, would make ...

The theory of Plate tectonics – developed from Alfred Wegener’s theory of Continental Drift to explain the movement of the continents – has become the prevailing theory underpinning our understanding ...
