Geologists have uncovered the remains of a massive tectonic plate beneath the Pacific Ocean, a plate that had been hidden for ...

Far beneath the ocean's surface, where mountain belts rise and ancient oceanic crust lies hidden, a long-lost tectonic plate ...

A fascinating new study reveals how two of Earth’s established continents may constitute one whole landmass in itself.

A research team found evidence that a plume of hot mantle and tectonic plates generate activity deep beneath the Afar region in Ethiopia, which will one day tear apart the African continent and create ...

Although evidence for this theory is based in the geologic record ... known as subduction “invasion” or “infection” where subduction—that is one tectonic plate sliding beneath another—sort of spreads ...

Plate tectonics, or the recycling of Earth’s crust, may have begun much earlier than previously thought—and may be a big reason that our planet harbors life ...

Plate tectonic theory is among the most brilliant insights in all of intellectual history because it so elegantly explains so much that for so long had eluded us.

Emerging evidence suggests that plate tectonics, or the recycling of Earth's crust, may have begun much earlier than previously thought — and may be a big reason that our planet harbors life.

Surprisingly, geologists don't have a good answer for when plate tectonics emerged, and estimates range from 700 million years ago to before 4 billion years ago, when Earth was still in its infancy.

Plate tectonics and complex life — If Venus had Earth-like plate tectonics in its distant past, did it have life too? — Do extraterrestrial auroras occur on other planets?

Plate tectonics is the theory that explains the structure and motion of Earth's outermost layer—the lithosphere—which is divided into several large and several smaller plates, like the cracked ...

Some 4.5 billion years ago, a Mars-sized object smashed into the nascent Earth, spinning off our moon. Now a team of scientists proposes this giant impact did even more: The collision left behind ...
