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...

Over 400 million years ago, an upwelling of hot rock from Earth's mantle wrenched apart the crust in Mongolia, creating an ocean that survived for 115 million years. The geological history of this ocean could help researchers understand Wilson cycles, or the process ...
Here’s how it works. A mantle plume tore a huge ocean into what is now Northewest Mongolia 410 million years ago. (Image credit: Halstenbach/Getty Images) Over 400 million years ago, an upwelling of hot rock from Earth's mantle wrenched apart the crust in Mongolia, creating an ...
basins, which are over 3,000 m/ 9,843 ft in depth. On the satellite image to the left, you can see the vertical (from top to bottom) light blue line in the deep blue sea. This is the boundary where the earth's continental places move apart, constantly creating new oceanic crust. ...
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...
However, crystallization of melts on the Moon occurs at an oxygen fugacity (fO2), much more reducing compared to the Earth’s mantle, which may limit the validity of the aforementioned predictive models without verification. The lunar mantle is significantly more reduced (given relative to the ...
A numeric modeling was used to clarify the possible role of internal tides and short internal waves in generation of the crust microdeformations. 展开 关键词: Lasers Physical oceanography Earth's atmosphere Numerical modeling 会议名称: SPIE Proceedings ...
