Plate tectonics is the theory that Earth's outer layer is made up of plates, which have moved throughout Earth's history. The theory explains the how and why behind mountains, volcanoes, and ...

This supercontinent formed hundreds of millions of years ago and helps explain why distant places share similar fossils, why ...

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 ...

Have tectonic plates changed speed over the last 3 billion years? The answer has far-reaching implications, as plate tectonics affected everything from the supply of vital nutrients for early life to ...

Researchers used small zircon crystals to unlock information about magmas and plate tectonic activity in early Earth. The research provides chemical evidence that plate tectonics was most likely ...

Travel brings many pleasures, but for those of us with an earth science background, it is a special treat to visit different ...

250 million years from now, the emergence of a new supercontinent could render most of Earth’s surface uninhabitable for mammals Up to 92% of Earth could be uninhabitable to mammals in 250 million ...

Earth's surface is broken up into large plates that rub against each other, causing earthquakes, volcanoes and large mountain ranges. But how unique is our planet's geology? When you purchase through ...

About 150 million years ago, a massive tectonic mega-plate stretched across the Earth, spanning roughly a quarter of the size of the Pacific Ocean. Its jagged contours ran all the way through the ...
