Their constant scraping and grinding have shaped the world we see around us. Now the tectonic plates that form the continents and ocean floors of our planet have been revealed in new detail in a ...

Plate boundaries are where the action is. A large fraction of all earthquakes, volcanic eruptions, and mountain building occurs at plate boundaries. It is also where most of the people on Earth live.

A study published in the Journal of African Earth Sciences sheds new light on the magnetic structure of the Afar region's crust and the process of the African continent's division.

The puzzle pieces of Earth's lithosphere are always in motion, slamming against each other and grinding past one another. Earth is action-packed. Even if there were zero life on our planet, the place ...

Researchers used small zircon crystals to unlock information about magmas and plate tectonic activity in early Earth. The research provides chemical evidence that plate tectonics was most likely ...

For years, many scientists had thought that plate tectonics existed nowhere in our solar system but on Earth. Now, a University of California, Los Angeles (UCLA), scientist has discovered that the ...

The emergence of plate tectonics is arguably Earth’s defining moment, the authors of a new Nature paper write. Out of all the planets we’ve looked at carefully, Earth is the only one that has a hard ...

The diagram below shows the structure of the earth. In geography, taking a slice through a structure to see inside is called a cross section. Continental plates are usually quite thick (between 35 to ...
