Even as you read this, Earth's crust is continually being reborn and recycled in a dynamic process that fundamentally shapes our planet. We're not generally aware of all this action because most of it occurs at the seafloor, under a formidable watery shroud, and often in remote regions of...

When the plates slip, vibrations are produced, and those vibrations travel through Earth's crust as earthquake waves. As the Pacific Plate descends into the mantle, it is heated by friction and the geothermal gradient. At a depth of approximately 100 miles, the rocks have been heated to a ...
Fully characterising the exchange of volatile elements between the Earth’s interior and surface layers has been a longstanding challenge. Volatiles scavenged from seawater by hydrothermally altered oceanic crust have been transferred to the upper mantle
crust- n. a hard, dry layer of the surface of something layer- n. an amount of something covering a surface ingredient- n. a part of something that makes it successful drill- v. to use a tool or machine to mak...
However, little is known about the mechanical properties of the asthenosphere (the part of the upper mantle below the lithosphere) underlying the oceanic crust, which covers about 60 per cent of Earth’s surface. Great earthquakes cause large coseismic crustal deformation in areas hundreds of ...
7. TheChallenger Deepin the Mariana Trench, which is located to the West of the Philippines and north of New Guinea, is the deepest point in the Pacific Ocean with 10,920 m/ 35,827 ft. It is the lowest part of the earth crust and was formed by the collision of two tectonic plates...
