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

Using information from inside the rocks on Earth’s surface, my colleagues and I have reconstructed the plate tectonics of the planet over the last 1.8 billion years. It is the first time Earth’s ...

It's the first time Earth's geologic record — information found inside rocks — has been used to create an animation of this kind. When you purchase through links on our site, we may earn an affiliate ...

200 million years ago, the planet looked very different than it did now. Plate tectonics had arranged the world's continents into a single massive landmasses: Pangaea. Today I attempt to use my ...

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 ...

This is how the western hemisphere of the Earth may have appeared 200 million years ago, with the supercontinent of Pangea stretching from pole to pole. In January 1912, the German meteorologist ...

For millions of years, Earth’s moving plates have sculpted continents, carved oceans, and built massive mountain ranges. Yet some of these giant structures vanished deep into the mantle, hidden from ...

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 ...
