The Mariana Trench is one of the deepest and most mysterious oceans on Earth. Situated at the bottom of the Pacific Ocean Northwest, it is a spectacular and mysterious sight.
The Mariana Trench is about 2,550 km long and more than 11 km deep. The water temperature is extremely low, the pressure is extremely high, and there is almost no light, which was once considered by scientists to be a place where species can barely survive.
However, in such a mysterious sea, human curiosity makes us constantly explore and discover many amazing things in it!
First, the Mariana Trench is a paradise for marine scientists, as it provides an extreme environment conducive to studying issues such as biological adaptation and marine geology.
Historically, scientists have repeatedly attempted to probe deeper into the Mariana Trench to understand the internal structure and dynamics of this uncharted area. In 1951, the first deep submersible Trieste successfully dived to the deepest part of the Mariana Trench, detecting a depth of 10,911 meters at the bottom of the area. With the continuous advancement of technology, modern deep submersibles have been able to detect deeper waters.
Second, life still exists in this deep sea, where the environment is extremely harsh. Due to the extremely high water pressure, extremely low temperature and large amounts of toxic gases such as methane and hydrogen sulfide, it is generally believed that there is no possibility of life here. But in reality, many exotic species have already been found here. The most famous of these is the Mariana Trench Star Shark, a shark that can survive at depths of up to 5,000 meters. In addition, scientists have also discovered some microorganisms such as protozoa and bacteria, which inhabit the high-pressure and low-temperature environment of the Mariana Trench, providing new insights into the nature and living conditions of life.
In addition, the geological formations in the Mariana Trench are one of the areas of interest to scientists. Because the trench is at a specific plate boundary location, earthquakes and volcanic activity occur frequently. Many geological formations can be observed from here, including ocean ridges, overflow basins, seamounts and volcanoes. The Mariana Trench is the deepest part of the ocean known to man, and even Mount Everest, the world's first peak, can easily be put into this vast and almost bottomless abyss.
About 60 million years ago, the Eurasian and Pacific plates collided here, and due to their high rock density and low location, they subducted and inserted under the continental plate, squeezing out a Mariana Trench more than 2,000 kilometers long and an average depth of nearly 8,000 meters. The hydrogen sulfide compounds and methane produced by the Mariana Trench could be one of the main sources of our future energy research, which is one of the reasons why scientists are interested in the region.
At the same time, humanity faces numerous challenges in the exploration of the Mariana Trench. The harsh underwater environment of the Mariana Trench, combined with extremely high water pressure and extremely low temperatures, makes the equipment required for expeditions very expensive and must be extremely technical and safe. In addition, the explorer's body is also exposed to great risks, because any small mistake can lead to disastrous consequences.
In conclusion, the mystery and depth of the Mariana Trench is amazing. In this deep sea full of unknowns, humans still have many questions to answer, which will promote our deeper understanding of the planet. However, we need to be aware that the Mariana Trench is the essence of the planet and needs to be protected to ensure that humanity can continue this unprecedented exploration work.
