It suggests that vast portions of the oceanic crust may harbor complex life forms, dramatically expanding the potential habitats for deep-sea creatures. This finding could revolutionize our ...

Surprising differences in the two so-called Large Low-Velocity Provinces may risk instability in Earth's protective magnetic field.

And like an eggshell, the crust has cracked and split into many different pieces called tectonic plates. These plates can be oceanic, meaning they're found mainly under the ocean, or continental ...

Deep trenches appear at these boundaries, caused by the oceanic plate bending downward into the Earth. Deep below the Earth's surface, subduction causes partial melting of both the ocean crust and ...

One common hypothesis is that the LLVPs are made up of oceanic crust that was pushed into the mantle at subduction zones. This crustal material was then stirred through the mantle over millions of ...

Drewitt, J. W. E., Walter, M. J., Zhang, H., McMahon, S. C., Edwards, D., Heinen, B. J., Lord, O. T., Anzellini, S., & Kleppe, A. K. (2019). The fate of carbonate in ...

Continental and oceanic plates all fit together to form the outer crust of the planet. Eight major plates are named on the diagram below. Heat from the core makes magma in the mantle rise towards ...

Others have suggested that the blobs are huge chunks of oceanic crust that were pushed into the mantle when one tectonic plate slipped under another — a process known as subduction. The crust ...
