The cooling time A c is defined as the time required for the oceanic plate to move from a spreading center to a trench, and is equivalent to the age of the oceanic plate when it just reached the trench. The assimilation time t m is defined as the time required for the subducting ...
So if an ocean floor tectonic plate meets the edge of a continent and they push against each other, the heavier one sinks down and goes under the other one. So the…um…the oceanic plate is made of denser and heavier rock, so it begins to sink down under the continental plate and ...
These inputs and outputs constitute a global deep-Earth water cycle, but quantifying the total water input from oceanic plates has proved difficult. Writing in Nature, Cai et al.1 report that the Pacific plate, which subducts in the Mariana Trench, contains much more water than was previously...
Considering Earth's polar flattening, a better approximation than a sphere of its mostly oceanic surface is an ellipsoid of revolution or spheroid (the term ‘ellipsoid’ is used here as conventionally used in physical geodesy). Such a surface is generated by rotating an ellipse about its minor...
new species,Tripneustes kermadecensisn. sp., is characterized by having ambulacral primary tubercles occurring on every fourth plate ambitally, flattened test with large peristome, one to two occluded plates for every four ambulacral plates, and complete primary series of interambulacral tubercles...
The glycoside hydrolase family 17 β-1,3-glucanase of Vibrio vulnificus (VvGH17) has two unknown regions in the N- and C-termini. Here, we characterized these domains by preparing mutant enzymes. VvGH17 demonstrated hydrolytic activity of β-(1→3)-gluca
The LV is also frequently impacted by tropical typhoons, heavy rainfall and landslides, and thus offers a remarkable natural laboratory to study tectonic, hydrological, subsurface and oceanic deformations and their short- to long-term interactions. Following their first installation in central Japan [7...
What is an example of oceanic oceanic convergence? Examples of ocean-ocean convergent zones aresubduction of the Pacific Plate south of Alaska (creating the Aleutian Islands)and under the Philippine Plate, where it creates the Marianas Trench, the deepest part of the ocean. ...
increase in aridity through mountain-building that favored the expansion of grasslands. Because the positions of continents in the Miocene world were similar to where they lie today, it is easiest to describe the plate movements and resulting changes in t...
The longevity of coherent eddies is, in turn, determined by the dissipation due to bottom and surface stresses, turbulence, and internal wave generation. [3] Large-scale vortical structure plays a key role in transport of properties in interior oceanic flow. Munk et al. [2000] reviewed ...
