The colossal movements of tectonic plates shape our world, influencing the composition of Earth’s atmosphere, the planet’s protective magnetic field and perhaps even the flourishing of life. Now ...

Magnetic crystals provide the earliest evidence yet of the plate tectonics that likely made Earth habitable, pushing its start back by 140 million years.

Picture the Earth’s crust and you most probably think of dense, dry rock. You don’t imagine a goey, honey-like substance trickling down into the planet’s deep underbelly. And yet, new research has ...

Researchers have made a new discovery that changes our understanding of Earth's early geological history, challenging beliefs about how our continents formed and when plate tectonics began. A study ...

An ancient slab of Earth's crust buried deep beneath the Midwest is sucking huge swatches of present-day's North American crust down into the mantle, researchers say. The slab's pull has created giant ...

PCWorld reports that scientists discovered Earth’s inner core has slowed its rotation relative to the crust, even appearing to stop moving in a phenomenon that occurs every 35 years. This iron-nickel ...

The study of polar motion and Earth's rotation dynamics encompasses the investigation of subtle shifts in the orientation of the planet's rotation axis relative to its crust. These motions are ...

Parts of ancient Earth may have formed continents and recycled crust through subduction far earlier than previously thought. New research led by scientists at the University of Wisconsin–Madison has ...

Modern continental rocks carry chemical signatures from the very start of our planet's history, challenging current theories about plate tectonics. Researchers have made a new discovery that changes ...
