The movement of Earth's plates -- the layers of rock that cover the planet's hot, flowing mantle -- produces these trenches, which can be almost 11 kilometers (7 miles) deep. The oceanic trenches are hemispheric-scale long but narrow topographic depressions of the sea floor. v.tr. Seaweed can be composed of brown, green, or red algae, as well as "blue-green algae," which is actually bacteria. This motion of plates result in different topological features on the Earth. by Senckenberg Research Institute and Natural History Museum.

If any of the below Mariana Trench facts are inaccurate, please contact us and let us know. In some cases, ocean trenches have become filled with sediment, in which case they are not readily identifiable as trenches, although investigation with radar and other imaging tools can reveal the underlying structure of the trench. spends her free time reading, cooking, and exploring the great outdoors. a type of electric light in which light is produced by a filament heated by electric current. es. These … These deep-sea canyons were originally called “deeps,” such as the Challenger Deep or the Horizon Deep. To think about the way in which ocean trenches form, it may help to have a visual aid; imagine sliding one hand under the other, and think about the trench which forms in the area where the hands meet.

Look it up now! hill on the seafloor near an ocean ridge, where the oceanic lithosphere begins to subduct beneath the overriding plate. The Earth’s crust is broken up into a series of massive sections called plates. The sides of the battery itself were armored with 160 millimeters (6.3 in) of wrought iron. Juveniles clean parasites and loose scales off of large fishes, including some that are predatory. The incredible depth of ocean trenches can also create a unique habitat which houses unusual ocean animals which prefer deep water; off the coast of Chile, for example, the fishing is quite good, thanks to a large ocean trench which is present in this area.
