The interiors of rocky planets and moons tend to be pretty hot compared with their surfaces. This heat, which can be caused by a number of sources — such as tidal stretching and compression, the ...

WASHINGTON — 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 ...

For decades, scientists have accepted a particular theory regarding the evolution Earth’s plate tectonics, but a recent study published in Nature Geoscience could defy this as a team of researchers ...

Rocks in Australia preserve evidence that plates in Earth’s crust were moving 3.5 billion years ago, a finding that pushes back the beginnings of plate tectonics by hundreds of millions of years.

On present-day Earth, plate subduction continuously modifies the chemical composition of the convecting mantle, and various mantle sources linked to these processes have been widely studied. However, ...

Earth's surface is a turbulent place. Mountains rise, continents merge and split, and earthquakes shake the ground. All of these processes result from plate tectonics, the movement of enormous chunks ...

His framework offered a new way to think about continental drift and revolutionized the study of earthquakes, volcanoes and evolution. By Clay Risen W. Jason Morgan, who in 1967 developed the theory ...

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 in the open access journal AGU ...

Plate tectonics may be unique to Earth and may be an essential characteristic of habitable planets. Estimates for its onset range from over 4 billion years ago to just 800 million years ago. A new ...
