The Mariana Trench is the deepest place in the world, so how deep is it? According to the published data, it can be concluded that the deepest is about 11km, so the trench is located in the Pacific region and is very close to Japan in terms of geography. Some we media even wrote that Japan is approaching the Mariana Trench and may eventually slide into it.
So is it true? In fact, there is not much research, but it can also explain a problem. The Mariana Trench is really deep enough to hold Japan. So what is under the bottom of the trench?
At the same time, the Mariana Trench has been confirmed to be able to accommodate Japan. If such a situation occurs one day, it means that great changes will take place between the ocean and the continent. The most intuitive thing is sea level, followed by coastal areas or many low-lying areas. At the same time, it should be a worldwide change. In fact, the Mariana Trench is not only a sea level, but also a coastal area or a lot of low-lying areas The formation of the trench is mainly due to the collision between the ocean plate and the continental plate, so this area is the big plate of the earth. Once the plate movement occurs again, the trench will change accordingly.
According to the existing geographical knowledge, we can know that the Mariana Trench is changing every day, because all the plates on the earth are moving every day, but the intensity is different. At the same time, different natural disasters will occur during the movement of these plates.
So will the Mariana Trench extend all the way down? In fact, this is entirely possible, because the two plates in the Mariana Trench have reversed, and the depth will continue to expand with the compression, and the plate rocks may fall off.
So it will deepen vertically, and will it reach the deep of the earth? In fact, the earth’s internal structure is divided into three parts: the core, the mantle and the crust. According to the data of Wikipedia, the average thickness of the crust is about 17 km, and the deepest of the Mariana Trench is 11 km, with a difference of about 6 km. Therefore, the distance between the Mariana Trench and the deepest of the crust is far away, and it is impossible to reach the geocenter for the time being. At the same time, our geocenter should actually reach the thickness of the mantle, so the available data of the mantle is large About 2800 km.
So does that mean that it’s really impossible for the Mariana Trench to reach the deepest part of the earth? In fact, it is unlikely. For example, one day, the earth’s plate movement – there is a special change, so the plate movement exists above the crust, so even if it continues to extend downward, the block is basically above the mantle, which means that it is still above 2800 meters.
So what’s in it? Why do experts worry about the creatures in the Mariana Trench?
Because this trench is the latest known area of the earth, many things can not be explored by human using cash technology. Of course, it also has creatures in shallow water area known to human.
According to the data recorded by HowNet, the life force of the creatures living in the Mariana Trench is very tenacious. For example, in 2014, scientists once found a kind of fish on the sea bed of 8145 meters. The record of this kind of fish will be about 500 meters deeper than the previous record of fish. Therefore, the discovery of the scientists is also a cause for concern
It’s a hot topic in the field of biology. It turns out that there are fish that can resist water pressure and have such a strong ability.
Because the Mariana Trench is very deep and bottomless, it is obvious that the water pressure is high and the temperature is low. At the same time, due to the above two conditions, low oxygen content, complete darkness and so on, it means that food is very scarce. Therefore, we can’t imagine that this is one of the areas with very bad environment on earth, but there are organisms in such a bad area In fact, the endurance of living things is far greater than that of human beings, which is much stronger than what human beings want. Therefore, maybe there will be different living things under the deeper trench, but now human science and technology have no way to explore them.
