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 ...

Emerging evidence suggests that plate tectonics, or the recycling of Earth's crust, may have begun much earlier than ...

The plate tectonics that determine the shape of our continents may have originated from a huge impact billions of years ago. This huge collision with the Earth, thought to have occurred around 4.5 ...

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 ...

A subduction zone near Cascadia is unraveling piece by piece. The process offers a rare glimpse into how tectonic plates die and form new geological boundaries. With unprecedented clarity, researchers ...

If you think about mountain ranges like the Andes or the Himalayas, you can come up with multiple factors that must affect their size and shape. There’s the collision of tectonic plates that squeezes ...

More specifically, they studied zircons in the 3.9–2.7-billion-year-old Saglek-Hebron Complex and 4.0–3.4-billion-year-old Acasta Gneiss Complex and found that instead of a linear progression of ...

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 ...
