Our planet has an outer layer made up of several plates, which move relative to one another. While we may take this knowledge for granted, this theory of plate tectonics was only formulated in the ...

Freelance writer Amanda C. Kooser covers gadgets and tech news with a twist for CNET. When not wallowing in weird gear and iPad apps for cats, she can be found tinkering with her 1956 DeSoto. Carole ...

The plate tectonics that determine the shape of our continents may have originated from a huge impact billions of years ago. This huge collision with the Earth, thought to have occurred around 4.5 ...

In 2021, geologists animated a video that shows how Earth's tectonic plates moved over the last billion years. The plates move together and apart at the speed of fingernail growth, and the video ...

It has been thought that plate tectonics were a significant factor in the shaping of our planet and the evolution of life. Mars and Venus don't experience such movements of crustal plates, but then ...

Plate tectonics is a highly complex phenomenon that underpins almost every geological process and our understanding of Earth. Increasingly sophisticated computers and statistical approaches, including ...

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. When you ...

In the desolate landscape of western Australia, a rocky outcrop that formed more than three billion years ago is giving geologists an unprecedented look at the early churnings of our planet. These ...
