An unexpected find in tiny crystals hints that the Earth's mantle may not quite behave as has been believed for nearly a century.

Earth’s solid outer layer, which includes the crust and the uppermost mantle ... works The driving force behind plate tectonics is convection in the mantle. Hot material near Earth's core ...

Cratons are fascinating yet enigmatic geological formations. Known to be relatively stable portions of the Earth's ...

Stable parts of the Earth's crust may not be as immovable as previously thought. While much of the crust is affected by plate tectonic activity, certain more stable portions have remained ...

The idea that the Earth's crust and mantle might move together like a "conveyor belt" as a result of convection currents in the latter was first proposed in 1919 by the British geologist Sir ...

One of the most puzzling phenomena lies beneath the Indian Ocean, south of Sri Lanka, where a massive gravity anomaly known as the Indian Ocean Geoid Low (IOGL) has confounded researchers for decades, ...

A ground-breaking discovery is sparking hope that geothermal energy at least five times more powerful than current wells could be on the horizon. The breakthrough comes thanks to "superdeep, superhot" ...

Plate tectonic theory is the scientific theory that attempts to explain why the Earth’s crust acts the way it does and produces the landforms we ... In 1929 Arthur Holmes, a British geologist, came up ...

Global warming caused vital Atlantic Ocean currents to collapse just before ... was a relatively warm stage of Earth's history characterized by higher temperatures, higher sea levels and smaller ...

Using a robotic arm equipped with a chisel, the submarine was able to extract several sections of the Earth’s crust, revealing the unexpected life forms beneath. “The cavities were filled with ...

Earth’s crust has undergone cycles of expansion and contraction throughout its history. These movements have altered the positions and topography of the continents, contributing to the current s ...
