Why is there a sea? Why love the sea

Science is not yet able to give a final answer to these questions, because they are linked to another universal and equally unresolved question of the origin of the solar system.

Research now proves that about 5 billion years ago, a number of large and small nebulae were separated from the solar nebula. They rotate while revolving around the sun. In the process of movement, they collide with each other, and some clumps combine with each other, from small to large, and gradually become the primitive earth.

During the collision of nebula masses, the sharp contraction under the action of gravity, coupled with the transformation of the internal radioactive elements, caused the primitive earth to be continuously heated and warmed. When the internal temperature reaches a high enough level, the substances in the earth, including iron, nickel, etc., begin to melt. Under the action of gravity, the weight sinks and tends to concentrate on the center of the earth, forming the earth's core; The lighter ones rise to form the earth's crust and mantle. At high temperatures, the moisture inside vaporizes and rushes out along with the gases and soars into the air.

But due to the gravitational pull of the center of the earth, they will not run away, and only around the earth, becoming a circle of air and water.

The water vapor entrained in the magma condenses, and water begins to grow on the earth's surface.

A layer of crust located on the surface of the earth, in the process of cooling and condensation, is constantly impacted and squeezed by the violent movement of the earth's interior, so it becomes folded and uneven, and sometimes it is squeezed out, forming ** and volcanic eruptions, spewing out magma and hot gas. At first, this happened frequently, but gradually became less and less common and slowly stabilized. This process of differentiation of light and heavy materials, resulting in great turmoil and great reorganization, was completed about 4.5 billion years ago.

Blazing magma rushes out of the earth's crust.

After the earth's crust has been cooled and shaped, the earth is like a long-left and dried apple, with a wrinkled and uneven surface. Mountains, plains, river beds, sea basins, all kinds of terrain are available.

For a long time, water vapor in the sky coexisted with the atmosphere; Thick clouds. As the earth's crust cools down, the temperature of the atmosphere slowly decreases, and the water vapor condenses into water droplets with dust and ash as condensation nuclei, accumulating more and more. Due to uneven cooling, the air convection is violent, forming thunder and lightning winds, torrential rain and turbidity, and the rain is getting heavier and heavier, and it has been raining for a long, long time.

The surging floods, through thousands of rivers, converge into a huge body of water, which is the primordial ocean.

In the pristine ocean, the sea water is not salty, but acidic and hypoxic. The water evaporates and rains on the terrain and falls back to the ground, dissolving the salt from the rocks on land and the seabed and collecting them in the seawater. After hundreds of millions of years of accumulation and fusion, it has become a roughly uniform salty water.

At the same time, because there was no oxygen in the atmosphere at that time, and there was no ozone layer, ultraviolet rays could reach the ground, and with the protection of seawater, life was born in the ocean. About 3.8 billion years ago, organic matter was created in the oceans, and there were lower single-celled organisms. In the Paleozoic Era, 600 million years ago, there were seaweeds, which photosynthesized in sunlight and produced oxygen, which slowly accumulated and formed the ozone layer.

At this point, creatures began to land on land.

It is the tears of lovelorn animals from ancient times to the present. And the saliva of animals in love...

Question 1: Why do people like the sea Because the sea is vast, if you look at the sea when you are in a low mood, it will make you open-minded, and when you are in a good mood, you can see the sea in a better mood, listen to the sound of the waves, and enjoy it on the beach, I like the sea, but I have never seen it once.

Question 2: Do you like the sea and why Do you like the sea because there are a lot of cute little animals in the sea.

Question 3: Why do girls like the sea? Like the sea is not only because it is beautiful, it is mysterious and more broad, so many girls like boys to have the same broad mind as the sea, question 4: why do many people like the sea The sea has a lot of fish.

Question 5: Why do I like the sea so much? Because the sea gives a lot of variety.

Listen to the sound of its waves. Very comfortable.

When the sea is angry. The waves crashed on the shore. It felt like it was defending itself.

Question 6: Why do many people like the sea It is because it is far away from the sea and has little contact. People who grew up near the sea don't love the sea as much.

When a person who loves you deeply changes for you, it is because he loves you, and when you meet someone, he puts away his stubborn temper for you; And because he loves you, he turns your interest into his interest when ......Or because he loves you.

There is no reason to like someone, and there is no regret to give.

They all think it's worth it, as long as they can be with the people they love.

In fact, we all have some such people around us, but (you. I. He hasn't discovered that the person who knows you best will always be by your side to protect you and not let you have a trace of grievances; People who truly love you may not say many things that love you, but they will do many things that love you.

If you find someone like this around you, please cherish .......

Please remember! The stars that can't be picked are always the brightest, and the small fish that slip away are always the most beautiful. The missed movie is always the best, and the lost lover always understands you best.

In this world, everyone has someone they want to find, and once they miss it, they won't come back.

If you fall in love, don't give up easily. It's awkward, maybe you regret it for a while; But you give up, and it may make you regret it for the rest of your life. A life that has experienced love is beautiful, and love that cannot stand the test is not profound.

Beautiful love enriches life, and love that has passed the test is perfect.

Adjectives preceded by two words:Blue sea, blue sea, vast sea, tumbling sea, turquoise sea, deep sea, magical sea, vast sea, vast sea, mysterious sea, calm sea, beautiful sea, vast sea, tranquil sea, stormy sea.

Fill in the first four-word adjective:The endless sea, the vast and boundless sea, the magnificent sea, the calm sea, the boundless sea, the rippling sea, the rough sea, the bottomless sea, the sea rich in resources.

Different people have different feelings about the sea

Many inland friends only stay in the description, film and television in the book and other people's **and**, but they have never witnessed the scenery of the sea in person, and they will feel that the sea is mysterious, beautiful, romantic, vast and thrilling.

In addition to the above feelings, being at the beach, listening to the sea habits, walking on the soft sand, watching the sunrise and sunset, I feel that all the troubles of life can be temporarily put down, enjoy a moment of tranquility, and feel the quiet life.

Those fishermen who often go out to sea to fish and live from the sea have a deep affection for the sea, which is an inseparable emotion. Every move of the sea may be related to the survival of fishermen, who have used the resources of the sea to feed generations of people, but during this period, many people have lost their lives because of the ruthlessness of the sea, so they have both respect and love and hatred for the sea.

For me, the sea is more of a romantic presence. During my relationship with my husband for a few years, I would go to the beach every National Day, although I went to a different place every time, but I gained a lot of romantic memories every time. My husband and I traveled for the first time to Cheung Chau Island in Hong Kong.

Wandering on the beach during the day, staying in a room with a sea view at night, sleeping to the sound of the waves; Our couple's wedding photos were taken on the seaside in Hainan, and the wedding photos were taken while playing, and the beauty was more beautiful, which left us with a lot of romantic and unique beautiful moments, which will become the most beautiful moment in my life.

The formation of the sea is that after the earth's crust has been cooled and shaped, for a long period of time, the water vapor in the sky and the atmosphere coexist in one mountain, and as the crustal hail slip gradually cools, the temperature of the atmosphere also slowly decreases, and the water vapor condenses with dust and volcanic ash as condensation nuclei, turning into water droplets, accumulating more and more. Due to uneven cooling, the air convection is violent, forming thunder and lightning winds, and surging floods, through thousands of rivers and ravines, converge into a huge body of water.

In the pristine ocean, the sea water is not salty, but acidic and hypoxic. The water evaporates and rains on the terrain and falls back to the ground, dissolving the salts in the terrestrial soil and the rocks on the seabed, and collecting them in the seawater. After hundreds of millions of years of accumulation and fusion, it has become a roughly uniform salty water.

To answer why there is a sea in the world is to answer where there is so much liquid water on the earth. There are generally two theories for all forms of water on the earth, one is that it is from the earth itself, which is compounded and decomposed to form more and more water, and the other is from the extraterrestrial water-rich substances or celestial bodies in the early days of the formation of the solar system and the earth, such as comets and some asteroids.

In the early days of the earth's formation, the surface temperature was relatively high, but after a long period of self-radiation and atmospheric movements, it gradually cooled down to meet the temperature of forming a large amount of liquid water. The fact that there was water on the earth in the early days does not mean that a large amount of water that was large enough to form oceans in the next billions of years of evolution of the earth can be preserved until now, just like Mars now, which has proven that there was water and even oceans in the early days of its formation, but now these are no longer there. Therefore, it is precisely because of the earth's unique natural conditions--- solar radiation, gravitational environment, the natural phenomenon of the change of seasons caused by the existence of the rotation and inclination angle, the gravitational pull of the moon, etc., that the earth has a relatively stable geographical system, including the long-term existence of the ocean.

In the early days of ocean formation, the sea water was sour and green, and that was because it contained a lot of iron ions at that time. Later, as the oxygen content of the atmosphere increased (and the oxygen content in the natural seawater also increased), the iron ions in the seawater were gradually oxidized and precipitated on the seafloor after a long time. Since then, the face of the ocean has been largely frozen, but of course there is still less marine life.

The sea is the home of the fish, and the sea is what the fishermen fill in

1. The sea is the home of the fish, and the sea is the place where the fishermen make their fortunes.

2. The sea is the home of the fish, and the sea is the paradise of happiness for fishermen.

3. The sea is the home of the fish, and the sea is the happy harbor of the fishermen.

4. The sea is the home of the fish, and the sea is the paradise of the fishermen.

5. The sea is the home of the fish, and the sea is the granary of the fishermen's life.

Tips for supplementing sentencesUnder normal circumstances, sentence sequencing or supplementing sentences is located in the third question in the accumulation and application of the first major question, and the multiple-choice question type or fill-in-the-blank question type is 2-3 points. From the stylistic point of view, in recent years, the questions in the secondary school examination are often mainly in the form of expository passages or argumentative passages, but the possibility of examining narrative passages in the future cannot be ruled out.

To answer this kind of test questions, you should first read through the given sentences as a whole to understand the general idea, clarify the main questions, grasp the general direction of sorting, and grasp the levels between sentences, such as: total score, juxtaposition, progression, transition, cause and effect, etc.

The permutations and combinations between sentences are in a certain order. Narrative passages are often based on the development of time, space or events: causes, processes and results as the order, for this kind of passage, you can start from the content of the events, the sequence of each episode, etc., when analyzing, you need to pay attention to those words that indicate the nature of time, direction, etc.
