Yale geophysicists reported that Earth’s ever-shifting, underground network of tectonic plates was firmly in place more than 4 billion years ago — at least a billion years earlier than scientists generally thought.
A new study by geochemists from Brown University suggests that Earth’s mantle varies in composition over kilometer-sized pockets. PROVIDENCE, R.I. [Brown University] — New research by Brown University geochemists provides new insights on the scale at which Earth’s mantle varies in … Continue reading →
Electrical Images Show Upward Flow of Fluids to Magma Chamber By measuring how fast Earth conducts electricity and seismic waves, a University of Utah researcher and colleagues made a detailed picture of Mount Rainier’s deep volcanic plumbing and partly molten … Continue reading →
A team led by researchers from the UCLA Henry Samueli School of Engineering and Applied Science has discovered that microscopic bacteria have a lot in common with earthquakes — when it comes to their jolting movements. In a new study … Continue reading →
The Earth is constantly manufacturing new crust, spewing molten magma up along undersea ridges at the boundaries of tectonic plates. The process is critical to the planet’s metabolism, including the cycle of underwater life and the delicate balance of carbon … Continue reading →
