Pangaea was a massive supercontinent that formed between 320 million and 195 million years ago. At that time, Earth didn't have seven continents, but instead one giant one surrounded by a single ocean ...

The continents we live on today are moving, and over hundreds of millions of years they get pulled apart and smashed together again. Occasionally, this tectonic plate-fueled process brings most of the ...

The idea that extreme climate change could one day cause a mass extinction and end the human dominance is not as farfetched ...

Earth's mass extinctions have come for the dinosaurs and a whopping 95 percent of ocean species. Mammals, like us, may be next — eventually. In intriguing new research published in the science journal ...

If you feel like you've had some drawn-out breakups, they probably have nothing on the supercontinent of Pangaea, which took tens of millions of years to split up. But now, a unique fossil skull might ...

The outer layer of the Earth, the solid crust we walk on, is made up of broken pieces, much like the shell of a broken egg. These pieces, the tectontic plates, move around the planet at speeds of a ...

The ocean is a big bathtub full of 326 million cubic miles (1.3 billion cubic kilometers) of water, and somebody has unplugged the drain. It's not a perfect system; scientists think there's currently ...

Researchers have found evidence that a part of Australia was once connected to North America, providing further insight to the ancient supercontinent known as Nuna. It may be hard to imagine that a ...

(CNN) — The formation of a new “supercontinent” could wipe out humans and all other mammals still alive in 250 million years, researchers have predicted. Using the first-ever supercomputer climate ...
