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

From time to time, when Earth's tectonic plates shift, the planet emits a long, slow belch of carbon dioxide. In a new modeling study published in Geochemistry, Geophysics, Geosystems, R. Dietmar ...

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 ...

A new study introduces a novel way for tectonic plates — massive sheets of rock that jostle for position in the Earth’s crust and upper mantle — to bend and sink. It’s a bit of planetary Pilates that ...

Let's get one thing out of the way: The supervolcano below Yellowstone is not going to erupt anytime soon; neither are any of the other similar systems that geologists have identified around the world ...

The present shallow marme biogeographic pattern is geologically transitory and reflects in large part the present state of the geography of continents and of lithospheric plate margins. Provincial ...
