Let's get one thing out of the way: The supervolcano below Yellowstone is not going to erupt anytime soon; neither are any of the other similar systems that geologists have identified around the world ...

Seismic waves from earthquakes have always offered a window into Earth’s hidden interior. For decades, researchers believed they had a firm grasp on how these waves revealed the rocky mantle’s secrets ...

Papers presented in a special symposium at the joint annual meeting of the Geological and Mineralogical Associations of Canada at St. John's in May, 1974. Tectonic settings for emplacement of ...

The colossal movements of tectonic plates shape our world, influencing the composition of Earth’s atmosphere, the planet’s ...

The rocks didn’t look like much from the outside. Scattered across a remote stretch of western Australia called North Pole ...

On Earth, the theory of plate tectonics describes the way large pieces of the planet’s crust move and interact. These pieces, or plates, slide over the mantle, the malleable outer layer of Earth’s ...

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 ...

A new study makes the case that the solar system’s hellish second planet once may have had plate tectonics that could have made it more hospitable to life. By Kenneth Chang Venus today is not like ...

Memorizing seven continents feels settled, like learning the alphabet. A new study argues the ground rules are less tidy. The work comes from the University of Derby, led by Dr. Jordan Phethean. His ...
