Our planet has experienced dramatic climate shifts throughout its history, oscillating between freezing "icehouse" periods ...

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

Climate change is usually associated with changes in atmospheric carbon dioxide, but our planet's surface also plays a major ...

Jupiter’s moon Europa may currently have little to no active faulting at its seafloor, according to a modelling study published in Nature Communications. This prediction challenges previous ...

WASHINGTON, March 4, 2025 – Seismology has revealed much of the basics about earthquakes: Tectonic plates move, causing strain energy to build up, and that energy eventually releases in the form of an ...

A hidden chunk of an ancient tectonic plate is stuck to the Pacific Ocean floor and sliding under North America, complicating ...

All the activity on Earth’s surface — erupting volcanoes, shifting tectonic plates, restless seas and myriad forms of life — depends on the two-part engine under the hood. Directly beneath Earth’s ...

Vast, quasi-circular features on Venus’ surface may reveal that the planet has ongoing tectonics, according to new research based on data gathered more than 30 years ago by NASA’s Magellan mission. On ...
