Scientists have long been puzzled by volcanoes that erupt far from the edges of tectonic plates—known as intraplate volcanoes ...

The mantle transition zone (MTZ), which occurs 410–670 kilometers below Earth's surface, may store several oceans' worth of water. This water, which is carried to such depths by subducting tectonic ...

New research suggests that Earth’s orbital variations—the slow changes in its tilt, axial precession, and shape of its ...

Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

At places where two tectonic plates are pulling away from each other, magma — hot, molten rock — can rise from the mantle to the surface, forming volcanoes. Volcanoes can also form where ...

It is widely believed that Earth’s atmosphere has been rich in oxygen for about 2.5 billion years due to a relatively rapid increase in microorganisms capable of performing photosynthesis. Researchers ...

New research from scientists with the Chinese Academy of Geological Sciences and published in the journal Science found that sample analysis backs up an established model of the moon as a global ...

Earth’s climate over millions of years is shaped by both internal forces, like volcanic activity, and external ones, such as ...

Io’s long-debated magma ocean may not exist. Juno spacecraft data reveals that tidal forces deform the moon differently than ...
