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

A simplified image of a slab from one of Earth's tectonic plates sinking through the upper mantle above, through the boundary between the upper and lower mantle 410 miles deep, then stalling and ...

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 ...

For millions of years, Earth’s moving plates have sculpted continents, carved oceans, and built massive mountain ranges. Yet some of these giant structures vanished deep into the mantle, hidden from ...

For millions of years, Earth’s shifting plates have shaped continents, formed oceans, and built towering mountain ranges. But ...

A 3D block diagram across North America showing a mantle tomography image reveals the Slab Unfolding method used to flatten the Farallon tectonic plate. By doing this, Fuston and Wu were able to ...

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 ...

Hell, or something like it, may be a little closer than we thought. As a new study published in Nature Geoscience reveals, geologists at Cornell and the University of Texas have discovered a “hidden” ...

Geologists have reconstructed a massive and previously unknown tectonic plate that was once one-quarter the size of the Pacific Ocean. The team had predicted its existence over 10 years ago based on ...

The world's highest mountain system may have reached 60% of its current elevation before the Indian and Eurasian tectonic plates crashed into each other, giving the peaks an extra push. When you ...

Researchers have examined tiny time capsules found in the oldest-known crystals in an attempt to settle a question that divides scientists: when did Earth’s tectonic plates begin to move? Plate ...

When tectonic plates sink into the Earth they look like slinky snakes! That's according to a study published in Nature, which helps answer a long standing question about what happens to tectonic ...
