What's in the underwater world

Question 1: What kind of details is the underwater world? What is the underwater world of 1? There are mountains, canyons, forests and grasslands under the sea. Plants have many colors, such as brown, purple and red. What a wonderful world! When the sea is rough, the bottom of the sea is still very calm. The biggest wind and waves can only affect tens of meters below the sea surface. Sunlight can't reach the bottom of the sea. The deeper the water, the darker the light. In this dark deep sea, there are many bright spots like twinkling stars, which are deep-water fish swimming with luminous organs. Is there no sound at the bottom of the sea? That's not true. Animals at the bottom of the sea often whisper to each other. As soon as you listen to the water receiver, you can hear all kinds of sounds: some are like bees buzzing, some are like birds chirping, some are like dogs barking, and some seem to be snoring. 2 0 1 3 02 03 4 04 05 5 06 07 6 08 09 7 10 1 1 8 12 13 9 14 15 10 16 / kloc-0/7 1 1 18 19 12 20 2 1 13 22 23 14 24 25 15 26 27 16 28 29 / kloc-0/7 30 3 1 18 32 33 19 34 35 20 36 2 1 37 22 38

Question 2: What creatures are there in the underwater world? Great white sharks, seahorses, groupers, turtles, walruses. Lion fish, electric eel

Question 3: What is the underwater world like? On our planet, the only place that humans have not conquered is the underwater world. Today's human beings have climbed Mount Everest, the highest place on earth, many times. After many times of space travel, the artificial probe has reached the outer space of the solar system. However, what the deepest part of the ocean looks like is still unclear. Because of the high cost of exploring the seabed, many problems are difficult to solve.

However, according to the information currently available, the rewards of exploring the underwater world will be extremely rich, because in this dark world, the reserves of minerals, natural gas and oil are very rich. In addition, the exploration of the wonderful world under the sea is likely to change our traditional view on the origin and evolution of life on earth. In addition to these tangible benefits, there are some intangible but tangible satisfaction, which is the great pleasure of exploring the last edge of the earth.

The ocean that has not been conquered by human beings so far accounts for 3/4 of the earth's surface, with a seawater volume of 654.38+0.4 billion cubic kilometers and an average depth of 3,700 meters. The intricate food web in the ocean breeds a wide variety of marine life, which is much more complicated than any ecosystem on land. From sulfur-eating microorganisms and bacteria living near the submarine crater to all kinds of deep-sea fish, their fluorescence can illuminate far away and attract many creatures to eat. In some places, there may even be a new species called "sea monster", including a 20-meter-long big black gun F.

Scientific research tells us that in this underwater world, the potential economic value is immeasurable: the vortex ocean current with huge energy affects the weather in most parts of the world. If we can understand their formation mechanism and laws, we can predict the occurrence of climate disasters and avoid trillions of dollars in economic losses. There are also huge nickel, manganese, iron, cobalt and copper with commercial development value in the ocean; Bacteria, fish and plants in the deep sea may become the source of magical drugs to protect human health and longevity. It is estimated that in the next few decades, the benefits brought by the ocean will far exceed the benefits brought by human exploration of space at present. If people can freely and safely enter and leave the seabed, its economic benefits will be immediate.

However, reaching the bottom of the sea is the same as reaching outer space. It is impossible for people to reach the bottom of the sea without special equipment. Common sense tells us that without the help of oxygen tanks, people can't dive into the water below 3 meters for a long time-this is only one third of the average depth of the ocean! With the continuous diving into the water, the pressure is getting bigger and bigger. People's inner ear, lungs and some pores will feel pressure and feel pain. When the underwater temperature is low, it will quickly absorb the heat of the human body. It is difficult for people to stay in water below 3 meters for 2 ~ 3 minutes.

For these reasons, contemporary deep-sea exploration has to wait for the development of two key technologies: deep-sea spherical submersible and deep-sea steel ball submersible tied with chains. People who can swim have been thinking about how to get oxygen underwater. It has been like this for thousands of years. In ancient Greece, divers got oxygen from bottles filled with gas, but in modern times, divers used compressed air to dive into human bodies. Usually people can dive to a depth of 30 meters. Even the most experienced people who use underwater breathing apparatus dare not venture to dive below 45 meters, because the increase of deep diving pressure and the pressure change in the process of floating to the surface lead to decompression sickness and even death. Using a sealed diving suit, you can only dive to a depth of 440 meters.

The spherical submersible created a depth of 923 meters, but it was very difficult to operate. Later, a small deep-sea submarine was invented, but it can only be used for scientific research. The advanced deep-sea submarine is equipped with underwater camera, specimen collection basket and manipulator with human hand function. The practice of submersible gives a positive answer. The United States, France, Japan, Russia and other countries have developed deep-water submarines for different purposes and collected data samples of animals, plants, rocks and water samples in the depths of the ocean. This opened a new era of deep-sea exploration. People have gained a lot of information in the deep-sea world, which has changed some traditional views of biology, geology and marine geography. Scientists look at the changing law of wind and current with new eyes; El Nino in the Pacific Ocean is very harmful to commercially valuable fish stocks, and it can also induce strange changes in the climate on the earth. The instability of ocean circulation may lead to global climate change, or make the stable climate on the earth slowly disappear.

Scientists also realize that the seabed at the bottom of the ocean is not flat, it is undulating and more complicated than our land topography, and its canyons can accommodate the Himalayas ...

Question 4: What cartoons are there about the underwater world? Finding nemo

The little mermaid

Question 5: What are the seaweeds in the underwater world? Some like what? Some are like what, some are like a few cute little hairballs, some are like holding up umbrellas, and some are like dancers dancing from a distance.

Question 6: What is the underwater world like? I have read many books about the beauty of the sea and heard the roar of the sea on TV. From then on, in my mind, there was a longing: how I wish I could see the sea with my own eyes! You can even see the crystal waves and soft beaches at a glance. This wish is rolling in my mind, which makes me full of infinite yearning for the sea.

Finally, this wish came true last May 1 Golden Week! My parents and I went to the seaside in Xiamen. As soon as I arrived at my destination, I couldn't wait to snuggle up in the harsh embrace of the sea and see the beauty of the sea with my own eyes. I put on my bathing suit and swimming ring, and called my father to take me swimming in the sea and feel the fun of the sea below. We set foot on the thin and soft beach. Suddenly, I stopped for a long time and looked at the blue sea. I can't help saying to the sea, "You are so beautiful! I love your beautiful sea! "

The next morning, the sky just announced that a red sun was rising slowly. I came to the seaside and looked into the distance. The boundless sea is connected with the blue sky, and the waves rise and fall with the sea breeze. Huge ships tore the sea water in two and marched bravely ... for a while, the blue sea was sprinkled with sand by the morning sun, flashing like countless little stars in the sky. A few seagulls crossed the Xia Hong in the early morning, flying freely, sometimes spreading their wings, and sometimes chirping happily, changing the ocean at dawn into new clothes. There are layers of waves on the sea surface, and the turbulent sea water hits the rocks and makes loud noises, splashing white foam. It's like playing a magnificent piece of music. We walked on the golden beach, and the waves followed us, scratching my feet, flapping my legs and spraying water on my face from time to time.

Then, we boarded Gulangyu and came to the door of the underwater world. I thought I was going to the bottom of the sea by submarine as soon as I opened it! In fact, the underwater world is like the "Dragon Palace" on land. Stepping into the door of the underwater world, I was presented with a huge two-story glass room. The house is very high, like a hall, with glass on both sides and the roof, one connected to the other, just like the Crystal Palace built in the sea. How beautiful! Standing in the middle of the house is like coming to the ocean. A circular glass column stands between the two floors of the underwater world, which looks like a "sea-fixing needle" to support this "Dragon Palace". It is transparent and shiny, and there are groups of fish swimming up and down. Seeing this column reminds me of the scene where the Monkey King went to the Dragon Palace in the East China Sea to borrow a golden hoop in "Brilliant Spring". I thought: is this a golden hoop? There are many rocks in the underwater world, and all kinds of corals grow on them: some are like blooming flowers, and some are like forked antlers. There are so many fish in the underwater world! Too many to count! In various ways, beautiful and strange. Fish swarmed through the coral. There is a big fan all over the body, which fans when swimming; Some have big mouths, as if they want to eat; Some eyes are round, full of thorns, as round as balloons. ...

I think the real sea will be as beautiful and strange as the underwater world.

I love your beautiful sea! I love you!
