The transition zone (TZ) is the name given to the boundary layer that separates the Earth's upper mantle and the lower mantle.It is located at a depth of 410 to 660 kilometers. The immense ...

Geophysicists have long theorized that the mantle transition zone, wedged between the upper and lower mantle at depths of 410 to 660 kilometers, could be a secret vault for Earth’s lost water.

A peaceful transition away from fossil fuels will require new global agreements on how to manage mineral resources in the deep ocean as well as those associated with continents.

We show that although intrusion of magma maintains crustal thickness during the early stages of the continent–ocean transition, ... Main Ethiopian Rift—southern Afar transition zone ...

The hotter temperatures of the transition zone likely facilitated an "upwelling" of hot rock from Earth's lower mantle to its upper mantle that actively pushed the plates apart, Agius said.

Experts say portions of the continent are pulling apart, creating the possibility that the Horn of Africa will become an island. This continent is slowly splitting apart, creating a new ocean Skip ...

Plate tectonics has its own version of the circle of life. Outlined by geologist J. Tuzo Wilson, the Wilson Cycle describes the birth and death of the ocean basins that separate continents.

The transition zone within which calcium carbonate increasingly becomes chemically unstable and begins to dissolve is called the lysocline. Because the ocean seabed is relatively flat, even a rise ...

A long-lost continent once sitting between India and Madagascar now lies at the bottom of the Indian Ocean, according to a report published Tuesday. Lewis Ashwal, a scientist at the University of W… ...

If this sample of ringwoodite is representative of the rest of the transition zone, says Keppler, “it would translate to a total of 1.4 × 10^21 kg of water — about the same as the mass of all ...

The African continent’s tectonic fate has been studied for several decades, but new satellite measurements are helping scientists better understand the transition and are offering valuable tools ...
