Our world’s surface is a jumble of jostling tectonic plates, with new ones emerging as others are pulled under. The ongoing cycle keeps our continents in motion and drives life on Earth. But what ...

A hidden shard of ancient crust has been detected where California’s San Andreas system collides with the Cascadia subduction ...

Memorizing seven continents feels settled, like learning the alphabet. A new study argues the ground rules are less tidy.

Geophysicists can use a new model to explain the behavior of a tectonic plate sinking into a subduction zone in the Earth's mantle: the plate becomes weak and thus more deformable when mineral grains ...

The tectonic plates are among the most powerful forces on Earth, exerting tremendous influence over every single life that unfolds on this planet. They are both creators and destroyers, capable of ...

Our world’s surface is a jumble of jostling tectonic plates, with new ones emerging as others are pulled under. The ongoing cycle keeps our continents in motion and drives life on Earth. But what ...

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 ...
