What are the peculiar sights of the deep sea? What do you think is the best thing about Deep Sea?

In this year's Spring Festival movies, we can say that we are like a cloud, such as Man Jianghong, who is now ranked first at the box office, and many people are looking forward to the Wandering Earth II, Exchange Life and Avatar II films, which I personally think is the most brilliant movie, it should still be the animated film Deep Sea.

Although this is an animated movie, I personally think that this animated movie is more suitable for adults, because through this movie, everyone can find their own shadow. The most brilliant thing about this movie in the deep sea should be that it pokes at the weakest place in everyone's heart, just like the protagonist of this movie, Betelgeuse, who has encountered certain setbacks and emotional neglect in life, which makes him fall into a confused and painful situation, and when he can't find an effective way, then he will make himself more painful and uncomfortable.

But because of the emergence of Nanhe changed Betelgeuse, although it is said that in order to save Betelgeuse, Nanhe finally sacrificed his precious life, but in the process, it also made Betelgeuse understand the meaning of life, let himself understand that everyone will encounter all kinds of setbacks, difficulties, and even all kinds of pain and torture in life, but as long as they can adjust their mentality well, carry out inner self-**, and insist on hope, then they can make a complete change in their lives. This movie also brings hope to many people who are confused and in pain, so I think this is the most brilliant movie of the year.

The ocean is divided into three layers: "ocean surface water" is the sea water with a depth of more than 200 meters; "Deep ocean water" is the sea water between 200 meters and 700 meters deep; "Deep ocean water" refers to the water at a depth of less than 900 meters.

Theoretically speaking, the "ocean depth" (matte layer) can be called below the compensated depth of the outer sea area of the continental shelf (i.e., the extreme depth of photosynthesis in the ocean, which is generally considered to be 200 meters as the limit).

Conversely, water shallower than 200 meters or more is called the "ocean surface" (photosphere).

The average depth of the world's oceans is 3,800 meters, and in a broad sense of oceanographic theory, 95% of the Earth's seawater is deep seawater. Since there is no clear boundary between the lighty and non-photospheres, there is actually a transitional layer between the surface of the ocean and the "deep ocean", that is, the "mid-ocean layer".

Extended Materials. The water in the sea always flows in a regular and definite form, and the cycle is endless, called ocean currents. One of the more famous is the Gulf Stream, which is 50 miles wide at its narrowest point and flows at speeds of up to 4 kilometers per hour, moving north along the coast of North America and across the North Atlantic Ocean, regulating the climate of northern Europe.

The North Pacific Current is a similar warm current that flows northward from the tropics and raises temperatures on the west coast of North America.

The prevailing winds are the main force that keeps the currents moving. The density of the sea is different, and the rapid shouting is also one of the causes of the current. Cold water is denser than warm water, so cold water sinks and warm water rises.

Based on the same principle, cold water near the poles also sinks and flows below the surface towards the equator. When it reaches the equator, this current rises in place of the warm water that flows to the poles with surface currents.

The coasts of the islands and the mainland also have an effect on the currents, either by directing the currents or by dividing them into tributaries. In general, however, the main currents circulate around the various ocean basins. Due to the Earth's rotation, ocean currents flow in a clockwise direction in the Northern Hemisphere and in the opposite direction in the Southern Hemisphere.

Scientists have discovered that the deep sea is not as barren and lonely as people think. Under the extreme pressure of the deep sea, there is still a world full of life.

On the surface of the earth, peopleThe atmospheric pressure we are subjected to is 1 atmosphere, which is 1 kilogram per square centimeter. The density of water is greater than that of air. If a person dives below sea level, the pressure of the sea increases by about 1 atmosphere for every 10 meters he sinks.

In the vicinity of the Galapagos Islands seafloor hydrothermal vents, where the pressure of the sea water reaches 250 atmospheres, equivalent to more than 250 kilograms per square centimeter. Scientists have analogized that such tremendous pressure is equivalent to putting an elephant on your toenail cover。The deep sea (often defined as the ocean at a depth of 200 meters below sea level) accounts for 2 3 of the habitable habitat on Earth, and the deep-sea environment is extremely harsh.

In the dark, icy depths of the ocean, the pressure of the sea is huge enough to compress a polystyrene foam cup to the size of a thimble.

The earliest research on the adaptability of marine organisms to pressure began in the late 70s of the 20th century, when scientists compared the proteins of shallow-water fish with deep-water spiny fish. Some scientists have also discovered that the key to the extreme stress of deep-sea animals is that they have a substance called lactate dehydrogenase (LDH) in their bodies - the LDH of Qixiao shallow-water fish can only adapt to lower pressures at depths of less than 500 meters; In contrast, the LDH of deep-sea fish is able to adapt to the enormous pressures of the sea at greater depths. At the same time,Piezolates were discovered to help deep-sea organisms adapt to stress, which effectively prevents the distorting effects of seawater pressure on proteins.

In addition, scientists have studied a molecule called trimethylamine oxide (TMAO) that shows:When TMAO is added to fish tissue samples, it can have a high and stable effect on proteins that are subjected to high pressure. Scientists have found TMAO in sharks, bony fish, crabs, and shrimp. In fact,It is also this substance that gives fish and shrimp a fishy smell

Scientists believe that the study of deep sea exploration can give us more insight into how marine life responds to the changing outside world. For the creatures that live in the ocean, since there is no way to avoid and escape these changes, they must learn to cope with and adapt to these changes.

Deep Mofeng Sea refers to the deep water in the ocean, which is located 200 meters to more than 1,000 meters below the level of the sea forest. Due to the extremely harsh environment of the deep sea, with little light and great pressure, there are many mysterious creatures and landscapes hidden in it.

There are many kinds of deep-sea life, including fish, molluscs, crustaceans, sea anemones, corals, etc. Some of these creatures are highly adaptable, such as black whales, giant octopuses, silver Arowanas, etc., and can survive in extremely low temperatures, high pressures, and dark environments; There are also creatures such as deep-sea insects, deep-sea shrimp, etc., that thrive in the deep sea through various special skills.

In addition, there are some amazing landscapes in the deep sea, such as submarine volcanoes, ocean trenches, and abyssal plains. These landscapes are also important for the study of marine geology, ecology and climate change.

In short, the deep sea is a field full of unknowns and mysteries, and the creatures and landscapes in it play an irreplaceable role in improving our scientific understanding.

What is the deepest part of the ocean? It's scarier than you think.

Mariana Trench, elevation: 11,034 m. It is more than 1,000 meters deeper than the deepest sea.
