What will happen if one day the oceans on the earth suddenly disappear?

For our earth, people's cognition obviously started from the earth. Man is an animal that lives on the earth. Before the emergence of civilization, they could make long-distance migration and exploration on the earth through their own strength. But no matter how we move forward in the world, the end result is to face the same thing-the ocean.

Therefore, in some civilizations, the earth is considered as a flat plate floating on the sea, and everything will eventually enter the ocean, and even the sun and moon will rise from the sea. This idea proves some simple materialism of the ancients. Although it is not completely correct, it also provides a reference perspective for human beings to explore the world.

With the development of science and technology, people already know that the earth is a planet revolving around the sun. The earth and the ocean are only a part of the earth. The ocean accounts for 70% of the earth's surface area, while the land is only 30%. We are now constantly exploring everything in the universe, including the ocean.

For human beings in the past, the ocean is a place full of wealth, but it also has various dangers. Up to now, people not only want to obtain resources in the ocean, but also want to know how the ocean is formed, how it changes and how it will affect our lives.

Humans don't live in the ocean, and the salt water in the ocean can't be directly drunk. When it comes to seafood, it's not that there is no substitute. In ancient times, people who had never touched the ocean in their lives lived a normal life. So, isn't the ocean important to human beings?

This problem needs to be divided into two situations. One is that the ocean is really not a "necessity" for human individuals, and it seems to be really dispensable from the personal resources we need to survive on the earth, but if we put the perspective on human beings as a whole, then the ocean is relatively important to us.

If the continent we live in is not separated by the vast ocean, then the story of the great voyage era will no longer be what it is today, and the history and development direction of mankind will also change. Of course, the ocean not only affects the development of human society, but also affects the environment we live in. The first life on earth was born from the ocean, which can be said to be the "hometown" of mankind.

But this is all the influence of the past. What would our life be like if the present ocean suddenly disappeared? Maybe it would be more convenient instead? The answer is of course no. If the earth suddenly loses its oceans, it will be an unprecedented disaster.

The earth is a rocky planet, but it is not a big stone with the same appearance and no change. The earth is rich in layers. We live in the outermost crust of the earth, and the ocean is also a part of the outer structure. If the ocean disappears instantly, there will be a huge depression on the earth's surface.

Although we are not actually in this big hole, the part that used to be sea water needs a lot of air to fill it, which will cause drastic changes in the global climate, first of all, the strong wind formed by the violent flow of air. We live in a world where there is always wind formed by airflow, but if the wind is too strong, it will form a wind disaster and destroy our home.

There have been countless windstorms in human history, and strong storms are like sudden waves that can crush everything. What is even more frightening is that the typhoon disaster when the ocean disappears will be much bigger than any typhoon disaster in history, and human beings may not be spared.

In addition to strong winds, the air pressure will also change. We usually use sea level as the standard to calculate the height of land. If the ocean disappears, the height of the area where we live will increase by nearly 4000 meters, because the difference in altitude is often reflected by the atmosphere. The original low altitude area will become high altitude, and the original high altitude area will be in the "high altitude".

The original plateau area is not suitable for many people's lives, and various altitude sickness will occur due to lack of oxygen. Needless to say, after the ocean disappears, the air at high altitude will be so thin that it can't breathe, not lack of oxygen, but suffocate.

Of course, besides oxygen content, there is another serious problem: temperature. We learned in middle school that every time the altitude rises 1000m, the temperature will drop by 6 degrees Celsius. Therefore, the temperature in the original plateau area will be greatly reduced and become unsuitable for human survival.

Apart from the atmosphere, water resources are of course one of the most affected parts after the disappearance of the ocean. Human life is inseparable from fresh water. At first glance, the disappearance of seawater like the ocean seems irrelevant, but in fact, the disappearance of seawater will also have a huge impact on freshwater resources. We now think that fresh water is "inexhaustible" because it participates in the water cycle of the whole earth.

Snow water is an important source of freshwater rivers, precipitation is formed by water evaporation into the atmosphere, and marine water resources are an important source. Once the ocean disappears, 97% of the earth's water resources will disappear. How long can fresh water resources exist?

In the case of rapid temperature drop, fresh water resources will exist in the form of ice and snow, just like the Antarctic continent, becoming a completely frozen world, and it is difficult for our previous water cycle to continue. Although most of the water is "sealed" on land, it does not mean that there is no drought crisis.

Because water no longer circulates, those places that are not close to the water system will fall into a dry and cold state, and even a fire will occur. After losing most of the water resources, a little flame will bring unprecedented disaster to our world. Especially after the volcanic eruption and other accidents, everything that can burn on the ground will be destroyed.

After the changes in the atmosphere and water resources, the seemingly stable atmosphere under our feet will also undergo tremendous changes. Some people may wonder, what is the relationship between the disappearance of the ocean and the ground formed by rocks? In fact, the earth under our feet is quite fragile, moving and changing at any time.

Once the seawater disappears completely, the weak part of the seabed crust will be deformed due to the loss of pressure, which will also drive the deformation of the continental plate, and there will be a major earthquake sweeping the world. Earthquake is one of the most terrible disasters for mankind, and this earthquake will be more violent than all the earthquakes we have experienced before.

A violent earthquake will destroy all our homes, and the current technology of human beings is not enough to resist such crustal movement. It can be predicted that if we don't master the technology of escaping from the earth before, then human beings will disappear completely under such a disaster, and it is even difficult to leave traces on the surface, because the crustal movement will profoundly change the present topography.

Not only human beings, but also most living things can't survive in such an environment, and the earth will become lifeless from this vibrant planet.

Although all the changes seem so terrible when the ocean suddenly disappears, this is a hypothesis after all, and the ocean will not really disappear suddenly overnight. But the earth is 4.6 billion years old and has experienced many environmental changes in its long life. The ocean will not remain the same forever in the future.

The sun is a star surrounded by the earth, and the change of the sun affects the operation of the earth all the time. People often imagine what changes in the position and relationship between the earth and the sun will bring. The Wandering Earth, for example, is such a work. So, is it just our imagination that the earth is in crisis because of the sun?

Actually, it is not. Through research, scientists have found that solar radiation is increasing in the macro direction and will have a more obvious impact on the earth. The sun is now in its heyday, but after its life as a star ends, it will gradually expand into a red giant and eventually devour the existing solar system.

Due to the increasing radiation intensity of the sun, the oceans on the earth will one day evaporate and disappear completely. However, compared with the possibility mentioned above, the ocean will gradually disappear. Of course, in either case, the disappearance of the ocean will also make life disappear together.

One of the most important reasons for the existence of life on earth is that we have a suitable position in the solar system, neither too close nor too far away.

If it is close, it will be too hot and there will be no liquid water, just like Mercury and Venus. If it is too far away, liquid water will freeze completely, unable to form an atmosphere to protect the planet's surface, and the temperature difference between day and night will become extremely extreme, just like Uranus and Neptune.

So the earth we live in seems ordinary, but it is actually the result of various "coincidences".

Since mankind successfully entered space, it has been exploring the "leftover goods" of the earth and trying to find another home for mankind in the universe. However, in decades of exploration, we found that there are many rocky planets like the earth, but few planets with suitable size, position and speed, at least there is no similar existence in the solar system. The nearest planet to the earth is Mars, but it can't let us immigrate directly.

As for places outside the solar system, human beings have not found a planet as habitable as the earth or even more habitable than the earth through observation, and our practical exploration ability is limited.

If the earth's environment continues to change in a direction unsuitable for human survival, it will eventually bring a devastating blow to mankind. Therefore, it is an urgent task for mankind to make our actions have a good impact on the earth as much as possible.

I can't let myself destroy the longer-term interests because of the immediate things. This is the performance of being responsible for yourself and for future generations.
