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 ...

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 ...

Long before the continents spread across the globe, Earth held one connected landmass known as Pangaea. This supercontinent formed hundreds of millions of years ago and helps explain why distant ...

Amongst the earliest of reptiles, dinosaurs, and large, vast forests of conifer trees, any animal on earth had one shared continent. We know it today as Pangea, a supercontinent that spanned from the ...

A new study suggests that plate tectonics -- a scientific theory that divides the earth into large chunks of crust that move slowly over hot viscous mantle rock -- could have been active from 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 ...

Some 4.5 billion years ago, a Mars-sized object smashed into the nascent Earth, spinning off our moon. Now a team of scientists proposes this giant impact did even more: The collision left behind ...

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 ...
