A study led by geophysicist Anne M. Hofmeister in Arts & Sciences at Washington University in St. Louis proposes that imbalanced forces and torques in the Earth-moon-sun system drive circulation of ...
An international team led by researchers from the Department of Earth and Planetary Sciences at The University of Hong Kong ...
Seismic waves from earthquakes have always offered a window into Earth’s hidden interior. For decades, researchers believed they had a firm grasp on how these waves revealed the rocky mantle’s secrets ...
In 2016, the geochemists Jonas Tusch and Carsten Münker hammered a thousand pounds of rock from the Australian Outback and airfreighted it home to Cologne, Germany. Five years of sawing, crushing, ...
New data indicating that Earth’s surface broke up about 3.2 billion years ago helps clarify how plate tectonics drove the evolution of complex life. In 2016, the geochemists Jonas Tusch and Carsten ...
