A small amount of molten rock located under tectonic plates encourages them to move. This is what scientists have recently discovered. Their new model takes into account not only the velocity of ...

Geophysicists have developed a new theory to explain the global motions of tectonic plates on the earth's surface. The new theory extends the theory of plate tectonics -- a kinematic description of ...

RUSSIAN RIDGE — At the summit of Rolph Hill, in a corner of the Russian Ridge Open Space Preserve closed to the public, stands an alien-looking machine — a small white dome balanced on three long ...

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 ...

In 2021, geologists animated a video that shows how Earth's tectonic plates moved over the last billion years. The plates move together and apart at the speed of fingernail growth, and the video ...

Our planet has an outer layer made up of several plates, which move relative to one another. While we may take this knowledge for granted, this theory of plate tectonics was only formulated in the ...

Earth’s crust looks solid from the surface, but it is broken into a shifting mosaic of slabs that slowly rearrange oceans and continents. Understanding how those tectonic plates first formed is one of ...

A massive 37-million-year-old underwater canyon reveals the fossil trace of an ancient Atlantic tectonic boundary.

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American A couple of weeks ago, I was writing up a ...
