A handful of ancient zircon crystals found in South Africa hold the oldest evidence of subduction, a key element of plate tectonics, according to a new study published in the open access journal AGU ...
The dance of the continents has been reshaping Earth for billions of years, creating the landscapes we walk on today. Scientists are unlocking secrets about how plate tectonics forged our modern world ...
It’s right there in the name: “plate tectonics.” Geology’s organizing theory hinges on plates—thin, interlocking pieces of Earth’s rocky skin. Plates’ movements explain earthquakes, volcanoes, ...
The early Earth may have looked much like Iceland—where lava fields stretch as far as the eye can see, inky mountainsides tower above the clouds and stark black sand beaches outline the land. But the ...
A long-standing question regarding the strength of olivine, the primary component of Earth's mantle, has now been answered. This study has implications for how we understand now tectonic plates form ...
From time to time, when Earth's tectonic plates shift, the planet emits a long, slow belch of carbon dioxide. In a new modeling study published in Geochemistry, Geophysics, Geosystems, R. Dietmar ...
Earthquakes and volcanism occur as a result of plate tectonics. The movement of tectonic plates themselves is largely driven by the process known as subduction. The question of how new active ...
Generally speaking, it’s easy enough to make sense of the last few million years of climate patterns—the world looked much as it does today, so changes in greenhouse gas concentrations or ocean ...
To learn why, where, and how earthquakes happen, you need to familiarize your students with the interior of the Earth and a model called plate tectonics. The engine behind the earthquake machine is ...
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, ...
Vast amounts of sediment eroded from Earth’s continents were necessary to lubricate the wheel of plate tectonics, scientists propose. The idea offers a new angle on long-standing riddles about the ...
