During our month of “What Ifs,” we’ve gone from doubling Earth to halving the Sun to everyone trying to jump at the same time, and we’re wrapping things up back at ground level: What if the ...

The continents as we know them resulted when the proto­continent Pangaea broke apart and its fragments made the long slow journey to their present positions. The process took about 200 m­illion years.

When the supercontinent Pangea began to fragment around 200 million years ago during the Early Jurassic, it reshaped the face of the planet. Vast new oceans opened, continents drifted apart and the ...

It's hard to imagine all of the world's land masses together as one supercontinent. Over 200 million years ago, however, that's what Earth looked like. The breakup of Pangea was essentially the first ...

For a long stretch of Earth’s history, the continents were not separated by wide oceans. They were joined into a single landmass known as Pangaea. It formed slowly, through collisions that took place ...

Recently, my team reported unprecedented evidence of a continental connection between the ancient landmasses Laurentia (North America) and Iberia (the northern margin of Gondwana) in the Late ...

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 oceanic crust produced by the Earth today is significantly thinner than crust made 170 million years ago during the time of the supercontinent Pangea, according to researchers. The thinning is ...

Earth’s plate tectonics could be a passing phase. After simulating rock and heat flow throughout a planet’s lifetime, researchers have proposed that plate tectonics is just one stage of a planet’s ...
