Elements of a newly discovered process in plate tectonics include a mass (rock slab weight), a pulley (trench), a dashpot (microcontinent), and a string (oceanic plate) that connects these elements to ...
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, ...
Every year, earthquakes shake the ground and volcanoes erupt around the edges of tectonic plates—the massive pieces of Earth’s crust that slide slowly across the planet, creating and destroying ...
The relationship between the sites means an earthquake in one zone can trigger an earthquake in the other in a phenomenon ...
Subduction zones, where one tectonic plate dives underneath another, drive the world's most devastating earthquakes and tsunamis. How do these danger zones come to be? A study in Geology presents ...
Plate tectonics in the Pacific and Atlantic during the Cretaceous period shaped the Caribbean region
The concurrent subduction of the Pacific and Atlantic plates resulted in the formation of a mantle plum and the ascent of magma. Credit: Nicolas Riel Earthquakes and volcanism occur as a result of ...
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, ...
Earth’s crust may have gone on the move roughly 3.8 billion years ago. “Earth is actually quite distinct to other planets, in that it has plate tectonics,” says study coauthor Nadja Drabon, a ...
Long-lost remnants of tectonic plates have been discovered sunken deep inside the Earth's mantle. These plate remains were found lurking underneath the center of other continental plates, far from ...
Geophysicists can use a new model to explain the behavior of a tectonic plate sinking into a subduction zone in the Earth's mantle: the plate becomes weak and thus more deformable when mineral grains ...
