The earth is no longer blue, so what is it that makes the earth change color?

Air pollution. Because the air now contains a lot of polluting gases and solid particles, which affects the color of the earth, it is air pollution that makes the earth discolored.

This is because the current carbon dioxide concentration is high, which has led to desertification in many parts of the earth, so it is generally yellow.

As the weather warms, sea levels are rising and inundating coastal strips, so the oceans are decreasing and the earth is less blue.

During the glacial period, the earth was milky white due to being covered by ice. After that, the earth is blue and green. Dark blue is the color of the sea, and emerald green is the hue of vegetation.

Before there were no people on the earth, and before primate animals evolved into adults, there were only animals on the earth, and animals were not easy to moveAnimals and green plants live in harmony, the surface layer of the land is covered by vegetation, and the green plants are relatively developed, all reaching tens of meters, and the animals are looking for food under the trees, playing games and entertainment. From the inside, it's emerald green. Therefore, the earth was preceded by blue and green desires.

The sky is bluer, the water is clearer, and all things in heaven and earth are vigorous and vibrant.

Viewed from outer space, the Earth resembles the deep ocean, showing a bluer, darker blue than it currently is. When you see the Earth from outer space, the Earth shows a beautiful dark blue color, and that's because everyone's Earth is a big "water polo game". On the surface of the earth, the deep sea occupies the surface of the earth, while the land occupies only the surface.

Therefore, the deep sea covers the vast majority of the earth's surface, and from outer space, of course, it is the hue of the deep sea - dark blue. When viewed from outer space, the earth has other hues except dark blue, which is the main color. A French astronaut flew in space for 25 days.

He said that the Earth is so beautiful from outer space that it really looks like a balloon.

It has a dark blue background color, but it has a different shade. In the Middle East, the Sahara Desert, the earth is bright red. Judging from the road surface, the earth is indeed colorful, with blue sky and white clouds, mountains, green mountains and green waters, and colorful biological worlds.

It is said that it was a photograph of the Earth taken by astronauts in outer space during the last daily mission of the Apollo spacecraft to explore the moon. It can be seen that the vast majority of the stars that people are trying to survive are dark blue, and there are also some emerald green, zongzi and white.

The human eye sees an object because the light source emitted from the object enters the human eye. The earth itself does not shine, and the human eye can see the earth, which is the natural light of the earth's reflective surface. Copernicus used experiments to confirm that natural light is composed of seven kinds of multichromatic light: red, orange, yellow, green, blue, indigo, and violetWhen natural light hits the earth's surface, it will be reflected and digested by the earth's surface.

There are also mountains and forests on the surface of the earth, and of course they show emerald green and rice dumplings. The temperature of the earth is constantly changing, and there are often clouds fluttering in the sky, which will send most of the natural light back to outer space, showing a milky white color.

Because the area of the earth's oceans and greenery is large and full of life, the main colors are blue and green. In primitive times, the earth was not like this.

This is because in addition to the land on the earth, there are many green plants on the earth, which will make the main colors of the earth observed in the universe blue and green; In primitive times, the earth was like this, because in primitive times, our earth had been separated from continents and oceans, so it was what we see now.

I think the main reason why the main colors of the earth are blue and green is that blue is the sea and green is the forest. In primitive times, the earth was not like this, because it was the earth's climate change was very extreme, which led to the appearance of the earth is not such a blue planet.

Many friends are space fans, always like to read some ** and books about the universe and the earth, many friends will find that looking at the earth from space, the earth is blue. Many of the ** about the appearance of the earth on the Internet are also cerulean blue. Why is that?

The composition of the planetFriends who have studied geography know that there are seven continents and eight oceans. The earth is made up of land and sea. Moreover, the volume of the earth is very large, and the proportion of human volume on the earth is very small.

We can't see humans in outer space because humans are so small. In space, we can only see some parts of the land and parts of the ocean. It is for this reason that the Earth looks blue in outer space.

Because the proportion of water in the surface area of the earth, that is, the area of the ocean, is very large. The color of the ocean is dark blue. As a result, the color of the Earth when we see it in space will turn blue.

The principle of optics <>

The earth's surface contains a variety of gases, including oxygen and carbon dioxide. There is also an ozone layer on the outside. When our eyes see colors through light, these colors are irradiated by the light, and due to the different gas compositions, the color information carried by the light through the various gases will also be biased.

So the color of the ocean, which we usually see with the naked eye, is dark blue. The color of the ocean seen in outer space is azure. This is because the reflection of light through a variety of gases causes some subtle changes in color.

When it is refracted into outer space, it becomes blue. But the overall will not deviate too much. In summary, these are some answers to the question of why the color of the Earth is azure when viewed from space.

Do you all understand? Do you know any secrets about Earth and space?

Because the atmosphere scatters sunlight, about 70% of the Earth's oceans are the color of the ocean.

Because of the refraction of light, it makes people look like the earth is blue, but the earth is not that color.

This is because many parts of the earth are oceans, so when you look at the earth from space, it looks like an azure color.

It's the color of the oceans on the earth, and the color of the oceans is blue, so it's the color that comes in.

People have the impression that the earth is often blue, compared to Mars, Jupiter and other planets, the earth feels very warm, and a lot of life is used on the earth, so a blue planet like the earth feels very kind, but the ** of the earth that people photographed in the last century is a piece of blue, but now half a century has passed, is the earth we live on now still a piece of blue?

Many people have been deceived by this phenomenon, in fact, the current earth has been very miserable, the blue has disappeared, and replaced by a gray, in fact, this is caused by human beings themselves, at that time human science and technology has not developed rapidly, human resources are also very limited, will not cause a large area of pollution to the earth such as air pollution such as environmental pollution, now we live on the earth has already been surrounded by some greenhouse gases.

And now the carbon dioxide content in the atmosphere is also soaring, which makes the global temperature continue to rise, and will cause more and more natural disasters, and there are many volcanic eruptions on the earth, and the harmful gases emitted by volcanoes are also sprayed into the atmosphere, causing secondary effects on the atmosphere, so now our earth looks like a gray piece, and it is no longer the blue planet in people's impressions. Especially when the satellite photographed a drifting continent near Hawaii in the United States, many people were very worried about the current environment of the earth.

Because the current drifting continent is not a real continent at all, but a pile of garbage floating into an area, and the area of this garbage is even larger than the land area of Japan, it seems that this artificial continent is still increasing in area, and now people must also pay some attention to this artificial continent, if human beings continue to indulge their behavior, it is estimated that after 50 years, the earth will become a gray planet. And there is not so much green, and even the earth is very likely to have a lot of disasters, and whether human beings can live on the earth at that time is one thing.

This is because more than 70% of the earth's surface is covered by seawater, and because the ocean is blue, the earth is a blue planet when viewed from space, which is very beautiful!

Because in recent years, the environment has been very polluted, and few people have paid attention to the ecological environment of the earth.

The earth is the place where we live, human beings can't do without the earth, so the earth is really good for us, we and the earth are inseparable, the earth is covered by a large area of ocean, everyone naturally thinks that the earth is a blue planet, but the earth is gradually turning from blue to green, what is the reason? Here's what it looks likeKnowledge of horoscopesLet's reveal it for everyoneThe reason why the earth has changed from blue to greenWhat color is the earth? I believe that many people will say that it is blue, after all, satellites have already taken a bird's-eye view of the earth, but in fact, the color of the earth will not change, right?

Because more than 70% of the earth is covered by the ocean, and the color of the ocean is mainly blue, so it is natural for everyone to think that the earth is a blue planet. However, the fact that the Earth is changing all the time from the satellites taken in the past and today, even from blue to green, also surprises scientists, so what is happening on Earth? With the development of society, the economy of all countries is improving at a high speed, and science and technology have also been greatly improved, but these high-tech developments have also had a certain impact on nature, such as:

Many industrial and mining enterprises have emitted various toxic substances into space and affected the atmosphere, thus aggravating the natural pollution of the earth, having a great or crooked impact on the earth, and causing a global warming scene, so that human beings have also been greatly affected, this phenomenon is also known as the greenhouse effect. In addition, with the widespread existence of the greenhouse effect, the sea level is also rising, and the phenomenon of ice and snow melting is also intensifying, so that the cities and countries in the coastal areas have also suffered a certain crisis, but this situation has not stopped or been controlled, but is still intensifying, which also makes human beings feel the crisis, and even relevant experts said that those coastal areas, the earth has not left them much time, so to find a reasonable solution, human beings can get out of trouble. In order to slow down this change, human beings are also vigorously rectifying the environment on the earth, such as cultivating various green plants, so that the increasing oxygen can also achieve certain effects, for example, China has cultivated thousands of trees in order to improve the increasing desertification, so as to improve the continuation of desertification in the relevant areas, so that the earth gradually becomes greener.
