Sentences with phrase «create subduction zones»
«Measuring the strength of olivine is critical to understanding how strong tectonic plates are, which, in turn, matters to how plates break and create subduction zones like those along the Cascadia plate, which runs down the west coast of Canada to the west coast of the United States,» said Warren, a geologist in the College of Earth, Ocean, and Environment.

The simulations show that mantle plumes and the weaknesses they create could have actually initiated the first subduction zones.
This subduction has created a collision zone with the potential to generate huge earthquakes and accompanying tsunamis, which happen when faulted rock abruptly shoves the ocean out of its way.
Hawai'i is especially vulnerable to a tsunami created by an earthquake in the subduction zone of the Aleutian Islands.
The deep mantle - derived buoyancy, together with plate cooling at the surface, creates negative buoyancy that together explain the observations along the East Pacific Rise and surrounding Pacific subduction zones.
In high - pressure and high - temperature X-ray measurements that were partly conducted at DESY, scientists created conditions similar to those in so - called subduction zones where an oceanic plate dives under the continental crust.
One way to learn more about the transformations in greater depths of subduction zones is to create similar conditions in the laboratory.
Near subduction zones, plates collide, forcing ocean crust down toward Earth's hot interior, where this crustal material melts, forming magma that rises buoyantly back to the surface and erupts to create volcanoes and seamounts.
[4] The ocean's influence extends even to the composition of volcanic rocks through seafloor metamorphism, as well as to that of volcanic gases and magmas created at subduction zones.
The deep mantle - derived buoyancy, together with plate cooling at the surface, creates negative buoyancy that together explain the observations along the East Pacific Rise and surrounding Pacific subduction zones.
