Sentences with phrase «subducted into»

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.»

Not exact matches

Often, one plate gets subducted under another and sinks into the mantle beneath, while elsewhere, new rocks rise to the surface.

Over long periods of time (think millions of years), the crust is subducted deep into the mantle.

While this would have steadily sunk into the mantle, it would not have caused the soft lithosphere to subduct and tear and therefore would not have produced plate margins.

It marks the plate boundary between the subducting Nazca plate and the South America plate, where the oceanic crust and lithosphere of the Nazca plate begin their descent into the mantle beneath South America.

The intermediate - depth regions of the subducting Nazca plate can be segmented into five sections based on their angle of subduction beneath the South America plate.

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

More perplexing still, seismic studies have shown no evidence that ocean crust is being subducted — thrust down into the hot mantle underlying the trench — which is the process that results in quakes at other deep - sea trenches.

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.

A numerical simulation shows how Earth's crust (blue) is subducted and transported into the mantle (orange).

The scientists believe the subducted area was absorbed into Europa's ice shell, which may be up to 20 miles (about 30 kilometers) thick, rather than breaking through it into Europa's underlying ocean.

Hydration reactions along the subducting plate are thought to carry water deep into the Earth, and dehydration reactions at greater depths release fluids into the overlying mantle that promote melting and volcanism.

Subducted - A geological process in which one edge of a crustal plate is forced sideways and downward into the mantle below another plate.

Some of the warm water would be subducted by Atlantic Meridional Overturning Circulation / Thermohaline Circulation, some would be carried by ocean currents into the Arctic Ocean where it would melt sea ice, and the remainder would be spun southward by the North Atlantic gyre toward the tropics so it could be warmed more by the effects of the slower - than - normal trade winds.

The back radiation which is entrained into the ocean bulk by wave action is minimal, because wave action subducts water which is well below the level back radiation can penetrate to (little more than its own wavelength).
