An enduring question in geology is when Earth’s tectonic plates began pushing and pulling in a process that helped the planet evolve and shaped its continents into the ones that exist today. Some ...

About 150 million years ago, a massive tectonic mega-plate stretched across the Earth, spanning roughly a quarter of the size of the Pacific Ocean. Its jagged contours ran all the way through the ...

Sept. 15 (UPI) --A new study suggests tectonic plates are weaker than previously thought. The findings, shared this week in the journal Science Advances, explain the discrepancy between rock strength ...

Researchers used small zircon crystals to unlock information about magmas and plate tectonic activity in early Earth. The research provides chemical evidence that plate tectonics was most likely ...

We often affiliate plate tectonics with earthquakes, as we are all taught in school that the shifting of plates leads to big shakes. But plate tectonics serve a far more important job to the planet ...

Utrecht University PhD candidate Suzanna van de Lagemaat has reconstructed a massive and previously unknown tectonic plate that was once one-quarter the size of the Pacific Ocean. She reconstructed ...

A scientist at the Johns Hopkins Applied Physics Laboratory is part of a team of researchers that found evidence of plate tectonics on Jupiter's moon Europa. This indicates the first sign of this type ...

Remember back in fourth grade when your mind was blown that the continents and oceans are all actually moving, very slowly, and that they used to be in different forms? The theory of plate tectonics ...

A new study suggests that tiny, mineral grains — squeezed and mixed over millions of years — set in motion the chain of events that plunge massive tectonic plates deep into the Earth’s interior. The ...

Since December 2025, a string of earthquakes has rocked northern Louisiana. Louisiana called on Tulane professor Cynthia ...

A geologic map of the Pilbara Craton in Western Australia. The rocks exposed here range from 2.5 to 3.5 billion years ago, offering a uniquely well-preserved window into Earth's deep past. The authors ...
