Using information from inside the rocks on Earth’s surface, my colleagues and I have reconstructed the plate tectonics of the planet over the last 1.8 billion years. It is the first time Earth’s ...

The Mid-Atlantic Ridge in Iceland. This area is the boundary between the North American and Eurasian tectonic plates, which move apart ~ 2.5 cm/year over millennia. When plate tectonics first emerged ...

That would have enabled more of this organic carbon—and carbonate accumulating in shallow water around Columbia—to be ...

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 ...

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 ...

For the first time in history, scientists have observed the rupture of a tectonic plate in a subduction zone in real time. The study, published in the scientific journal Science Advances, was ...

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 ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. Are we alone, and if so, why? So far, the search for ...

For years, many scientists had thought that plate tectonics existed nowhere in our solar system but on Earth. Now, a UCLA scientist has discovered that the geological phenomenon, which involves the ...
