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 same geologic forces that stitched the supercontinent Pangea together also helped form the ancient coal beds that powered the Industrial Revolution, report researchers. The consolidation of the ...

The existence of the supercontinent Pangea, which formed about 300 million years ago and broke up about 200 million years ago, is a cornerstone of plate tectonics, and processes resulting in its ...

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 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.

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 ...

Plate tectonics was founded in the late 1960s, and it concerns the distribution and movements of plates, the uppermost layer of the Earth. Plate movements not only control the distributions of ...
