Scientists discovered plate anomalies in Earth's mantle using seismic wave analysis. These mysterious structures challenge tectonic theories.

Earth is estimated to be 4.5 billion years old, but understanding when it evolved from a sizzling hot ball to a planet that could host life is a little more difficult. Earth is estimated to be 4.5 ...

Researchers have produced a new estimate for the origin of Earth's plate tectonics—the movement of large chunks of the planet's outer layer, or crust. Although there is broad consensus that plate ...

A new study carried out on the floor of Pacific Ocean provides the most detailed view yet of how the earth’s mantle flows beneath the ocean’s tectonic plates. The findings, published in the journal ...

It's the first time Earth's geologic record — information found inside rocks — has been used to create an animation of this kind. When you purchase through links on our site, we may earn an affiliate ...

A new study of rocks that formed billions of years ago lends fresh insight into how Earth's plate tectonics—the movement of large pieces of Earth's outer shell—evolved over the planet's ...

This video excerpt from NOVA: "Deadliest Earthquakes" shows how Earth’s crust is made up of rocky slabs, called plates, and how those plates are constantly moving. As molten rock rises from Earth's ...

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 ...
