What is an ocean ditch?

Ocean ditch is a geological structure that occurs underwater along the boundary of the tectonic album. Specifically, there are ocean trenches along the subduction zones, in areas where one plate is sucked under another. The largest of these trenches are in the Pacific Ocean, where many active subduction zones have been identified, but smaller trenches can also be seen in the Indian and Atlantic Ocean. You could consider the ditch of the ocean for the type of underwater valley. If you want to think about the way in which ocean trenches are formed, it can help with visual help; Imagine that one hand is slipping under the other and think about a ditch that is formed in the area where the hands meet. This miniature ditch is identical to the trenches that are formed in subduction zones. The new material to be downloaded is constantly generated on the oceanic ridges, where the seabed is constantly spreading with fresh rocks under the earth's bark. Numerous other trenches cross the Pacific and appear along the edge of South America. In anyThe trenches on the oceans are filled with sediment, in which case they are not easily identifiable as trenches, although radar investigation and other imaging tools can detect the basic structure of the ditch.

are usually ocean trenches near the volcanic activity because volcanoes are very common in subduction zones. The incredible depth of ocean trenches can also create a unique habitat in which unusual animals of the ocean are located, which prefer deep water; For example, off the coast of Chile, fishing is quite good, thanks to the large ditch of the ocean, which is present in this area. The depths of the ocean ditch are some very interesting challenges for sea animals, because the trenches are extremely dark and very cold and the pressure overlapping seawater is intense. Organisms that adapted to this environment have some remarkable features.

examinedThe mapping of ocean trenches represented some challenges for people. People are unable to handle a dark, cool, high -pressure trenches and most of the survey were carried out using imaging devices and robotics. People descended into the Marian ditch in specially equipped submarines, but did not stay long.
