When plate tectonics emerged in the 1960s it became a unifying theory, “the first global theory ever to be generally accepted in the entire history of earth science,” writes Harvard University science ...
Ancient plate tectonics in the Archean period differs from modern plate tectonics in the Phanerozoic period because of the higher mantle temperatures inside the early Earth, the thicker basaltic crust ...
Be sure to watch GMSA@9 on Wednesdays, when KSAT Meteorologist Sarah Spivey demonstrates and explains the science behind it.
On present-day Earth, plate subduction continuously modifies the chemical composition of the convecting mantle, and various mantle sources linked to these processes have been widely studied. However, ...
Robyn Williams: In Perth we have a leading geologist who came originally from Germany. His name is Klaus Regenauer-Lieb and he has just scored a cover story in the journal Nature. It's about the way ...
A hidden chunk of an ancient tectonic plate is stuck to the Pacific Ocean floor and sliding under North America, complicating earthquake risk at the Cascadia subduction zone.
The world's highest mountain system may have reached 60% of its current elevation before the Indian and Eurasian tectonic plates crashed into each other, giving the peaks an extra push. Researchers ...
Plate tectonics can trigger ice ages through the production of the carbon-trapping mineral smectite, according to a new study. MIT geologists have found that a clay mineral on the seafloor, called ...
Early in Earth’s history, the heat left over from the collision that formed the Moon left its surface an ocean of magma. As it cooled, its crust was frequently shattered by massive impacts that ...
University Geophysicist W. Jason Morgan GS '64 received the National Medal of Science at a White House ceremony on Nov. 6. In addition to the groundbreaking work prompting the honor, Morgan, who plans ...
