New crust is continually being pushed away from divergent boundaries (where sea-floor spreading occurs), increasing Earth's surface. But the Earth isn't getting any bigger. What happens, then, to keep ...

New experiments have re-created the genesis of Earth’s first continents. By putting the squeeze on water and oceanic rocks under intense heat, researchers produced material that closely resembles the ...

Professor YAO Huajian's research group from the School of Earth and Space Sciences of the University of Science and Technology of China (USTC), in cooperation with Dr. Piero Poli from Grenoble-Alpes ...

The oceanic trenches are hemispheric-scale long but narrow topographic depressions of the sea floor. They also are the deepest parts of the ocean floor. Trenches define one of the most important ...

Researchers report in Nature that an approach used for years to understand the structure of Earth's oceanic crust is flawed and geoscientists will have to reconsider the correspondence between seismic ...

The two large low-shear-velocity provinces (LLSVPs) of the lower mantle 7,8,9 are hypothesized to be caused by large accumulations of intrinsically denser, more primitive material 10,11,12,13,14, ...

Learn about the swelled-up structure beneath Bermuda, where a thick layer of buoyant rock may be holding up oceanic crust. The Bermuda Triangle has been the source of tall tales for decades, but deep ...
