Tectonic plates: can’t live with them, can’t live without them. Their movements cause some of the world’s deadliest disasters, but, as you’re about to see, the alternative is much, much worse.

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 ...

In a new study, a team of researchers suggests that 4 billion years ago, plate tectonics likely looked closer to what we experience today than previously thought. The team published its findings in ...

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 ...

The plate tectonics theory established in the 20th century has been successful in interpreting many geological phenomena, processes, and events that have occurred in the Phanerozoic. However, the ...

Our world’s surface is a jumble of jostling tectonic plates, with new ones emerging as others are pulled under. The ongoing cycle keeps our continents in motion and drives life on Earth. But what ...

For years, many scientists had thought that plate tectonics existed nowhere in our solar system but on Earth. Now, a UCLA scientist has discovered that the geological phenomenon, which involves the ...

Bryan Isacks, a Cornell geophysicist whose landmark research helped establish plate tectonics as a foundation of modern geology, died Sept. 9 in Ithaca. He was 90.

Until recently, researchers believed only one planet in our solar system had plate tectonics: Earth. But in a recent study, Brown University researchers used atmospheric modeling to show that Venus, ...
