Sentences with phrase «as subducting»

However, one potential criticism is that the model (the Cane - Zebiak model) does not allow for important extratropical feedbacks such as subducting water masses from the extratropics that eventually can influence the equatorial Pacific thermocline.

As the subducting plate sinks deeper into the earth, it encounters higher and higher temperatures and pressures, which release the significant amount of water trapped in waterrich minerals that exist within the slab.

Deep earthquakes, also called intraplate quakes, take place within the oceanic Juan de Fuca plate (beneath Oregon and Washington) and the Gorda plate (beneath northwestern California) as they subduct beneath the North America plate.

Not exact matches

The Andes were formed by tectonic activity whereby earth is uplifted as one plate (oceanic crust) subducts under another plate (continental crust).

«Tearing and breakoff of the subducted slabs as the result of a collision of the Panama arc - indenter with northwestern South America,» appears in the June 2013 issue of BSSA.

Earthquakes can also be generated to depths greater than 600 km as a result of continued internal deformation of the subducting Nazca plate.

Large intermediate - depth earthquakes (those occurring between depths of approximately 70 and 300 km) are relatively limited in size and spatial extent in South America, and occur within the Nazca plate as a result of internal deformation within the subducting plate.

Using GPS, InSAR, gravity, seismic reflection, and geological data, Marcos Moreno and colleagues from GFZ as well as Chile show that the 2016 earthquake occurred at the deep boundary of a persistent asperity on the interface between the subducting Nazca and overriding South American plates, where both plates are coupled and not sliding past each other in spite of the high convergence velocity of 68 mm / year.

As the model helps explain, a volcano can form inland if the slab subducts at a shallower angle, and a hole in the shallow slab allows for a special type of magma to form by melting of the crust.

At subduction zones such as these, an oceanic tectonic plate sinks (subducts) into the Earth's interior, the mantle.

However, the mantle remained so hot that it softened the subducting oceanic crust too much for it to pull large areas of continental crust down behind it, as it does today.

At certain subduction zones, such as those in Cascadia, Sumatra and eastern Alaska, a thick sediment layer overlies the subducting oceanic plate.

As a result, mantle plumes entrain a variable combination of relatively young oceanic crust directly from the subducting slab, older oceanic crust that has been stirred with ancient more primitive material and background, depleted mantle.

As long as rapid continental weathering continued, carbonate was deposited on the oceanic crust and subducted into what Lowe calls «a big storage facility... that kept most of the carbon dioxide out of the atmosphere.&raquAs long as rapid continental weathering continued, carbonate was deposited on the oceanic crust and subducted into what Lowe calls «a big storage facility... that kept most of the carbon dioxide out of the atmosphere.&raquas rapid continental weathering continued, carbonate was deposited on the oceanic crust and subducted into what Lowe calls «a big storage facility... that kept most of the carbon dioxide out of the atmosphere.»

These great quakes often take place at subducting tectonic plate boundaries, where one plate thrusts beneath another plate, as is the case off the coast of Chile and the U.S. Pacific Northwest.

The subducting plates do not slip continuously; instead, the plates are stuck together along the upper portion of the subduction fault, which is referred to as «locked zone.»

The logic is that it would have been subducted as a function of plate tectonics billions of years ago, then encased in a forming diamond deep in the mantle, and ultimately sent back up near the surface again.

As this heat moves counter-clockwise around the Arctic Ocean to the north of Siberia and Alaska, it subducts, that is, it is covered by cold water that floats above the warm Atlantic water.

Why didn't the Atlantic SST simply cool as heat was being subducted in its basin?

Also, it needs to be understood that eastern boundary currents are part of this meridional overturning circulation (transport and upwelling of water originating as polar water previously subducted)

The CO2 tectonic source grew from 60 to 50 Myr BP as India subducted carbonate - rich ocean crust while moving through the present Indian Ocean prior to its collision with Asia about 50 Myr BP [8], causing atmospheric CO2 to reach levels of the order of 1000 ppm at 50 Myr BP [9].

Extratropical ocean influences are also likely to play a role as changes in the ocean gyre evolve and heat anomalies are subducted and re-emerge (Deser et al., 1996, 1999, 2003; Gu and Philander, 1997).

With Venus storing up enough heat so as to finally subduct its entire surface when it got so much heat energy that it couldn't hold it any more.

Therefore, where tectonic plates collide, and one is subducted, it must be subducted faster as the crust shrinks.

However, it must be borne in mind that the MOC can also include shallower, wind - driven overturning cells such as occur in the upper ocean in the tropics and subtropics, in which warm (light) waters moving poleward are transformed to slightly denser waters and subducted equatorward at deeper levels.
