Alfred Wagner proposed a theory in 1912 that paved the way for plate tectonics. Wagner’s concept of continental drift was used to explain what happened when the supercontinent of Pangaea broke ...

All of these processes result from plate tectonics, the movement of enormous chunks of Earth's crust. This movement may be why life exists here. Earth is the only known planet with plate tectonics ...

From the deepest ocean trench to the tallest mountain, plate tectonics explains the features and movement of Earth's surface in the present and the past. The theory of plate tectonics was ...

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.

This process, called plate tectonics, is responsible for earthquakes, volcanoes, ocean ridges and vast mountain ranges on Earth's surface. We know that other rocky bodies, such as Venus ...

Computer simulations suggest that a collision with another planetary object early in Earth’s history may have provided the heat to set off plate tectonics. By Lucas Joel Some 4.5 billion years ...

Past evidence suggests mechanisms in early Earth's mantle that kicked off subduction, the geological process where one tectonic plate sinks under another into the mantle below, began just 200 million ...

Now a team of scientists proposes this giant impact did even more: The collision left behind mysterious blobs within Earth’s interior that may have helped kick off plate tectonics — the ...

While it's the reigning theory now, the road to acceptance was long and bumpy for plate tectonics, which describes how large portions of Earth's crust slide, grind, rise and sink ever so slowly across ...

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 ...
