Ancient Earth’s hot interior created ‘graveyard’ of continental slabs

Plate tectonics has shaped the Earth's surface for billions of years: Continents and oceanic crust have pushed and pulled on each other, continually rearranging...

How continents were recycled

Researchers from Germany and Switzerland have used computer simulations to analyse how plate tectonics have evolved on Earth over the last three billion years....

Scientists set sail to unlock secrets of ‘lost continent’ Zealandia

Scientists are attempting to unlock the secrets of the "lost continent" of Zealandia, setting sail Friday to investigate the huge underwater landmass east of...

Link identified between continental breakup, volcanic carbon emissions and evolution

Researchers have found that the formation and breakup of supercontinents over hundreds of millions of years controls volcanic carbon emissions. The results, reported in...

Geology and biology agree on Pangaea supercontinent breakup dates

Scientists at The Australian National University (ANU) have found that independent estimates from geology and biology agree on the timing of the breakup of...

As continents continue moving, study suggests effects on biodiversity

Continental drift and plate tectonics—the notion that large chunks of Earth's crust slowly but inexorably shift positions—was proposed in 1912 but not accepted until...

Continental crust thanks to the right mixture

For the first time, ETH scientists have successfully recreated the formation of continental crust in the Archean using a computer simulation. The model helps...

A new interpretation of petrogenesis of Earth’s early continental crust

The Earth's continental crust was mainly formed in the Archean period, ~2.5 to 4.0 billion years ago, and is chiefly composed of tonalite, trondhjemite...

“Lost continent” found under Mauritius

Scientists have confirmed the existence of a "lost continent" under the Indian Ocean island of Mauritius that was left-over by the break-up of the...

Where’s the center of North America? Geographer’s new method finds a...

Where is the geographic center of a state, country or a continent? It's a question fraught with uncertainty. Do you include water in your calculation?...
