What if the world were free of dust

Dust may seem annoying to us now, but it has a certain effect on us.

If there is no dust, then the sun's rays will shine directly on us, then we will become black Africans, and not only that, but we may also suffer from ** cancer.

At some point, dust adds a hazy beauty to nature or to our vision. If there is no dust, then there is one less strange experience in our lives.

In our city, there is a lot of dust pollution. If there were no dust, our streets would be cleaner.

If there is no dust in the atmosphere, strong sunlight will make it impossible to open one's eyes.

If there is no dust in the atmosphere, the entire sky will always be blue due to the scattering of sunlight by only gases.

If there were no dust in the air, everything on the ground would be wet.

If there is no dust in the air, it is difficult to form rain and snow in the sky to regulate the climate

There are a lot of bacteria, viruses, pollen, very small garbage ...... in the dustWithout these things, people may not have allergies and will not be so prone to colds.

There are no bad weather like sandstorms.

However, many wind-borne flowers will not be able to bear fruit and reproduce to the next generation, so there will be a lot of rare and beautiful flowers that will bloom as a result.

And the light passing through the gaps in the leaves will not form that kind of beautiful light, because without the refraction of dust, the light will not be visible......

Please keep up playing :)

There will be a blue sky, there will be no water, the light will be very large, and it will burn the eyes.

The sun's rays shine directly on the earth, causing great harm to people's **, everything has its two sides, and dust prevents the sun's rays from reaching the atmosphere directly to a certain extent.

Where light can't be found, it's pitch black

Wouldn't there be no such thing as rain in the world, hehe.

That means that every place is moist or watery. Otherwise, there is no temperature.

The world will become wet, and it will be either too dark or too bright. The ** of the dust is dirt.

finely dried powdered particles of soil or other substances; something that has been reduced to a tiny part; Fine powder.

Dust is the enemy of human health, so people especially hate it because it carries many bacteria, viruses and insect eggs everywhere and spreads diseases. Industrial dust and fine dust can make workers suffer from a variety of difficult occupational diseases, excessive dust can also cause environmental pollution, affect people's normal life and work, induce human respiratory diseases and so on.

However, the credit of dust must not be erased. If there is no dust in the atmosphere, sunlight cannot be absorbed, reflected, scattered and refracted, and the sky is either too bright or too dark. Since dust is a hygroscopic particle, without its core, the water vapor in the air cannot condense, and it is difficult for clouds in the sky to form, and the surface of the earth will become arid and barren without the cover of clouds, and the weather will either be too hot or too cold.

Without dust, many harmful rays in the universe would break into the Earth's surface unhindered and pose a deadly threat to humans and various living beings.

Although dust has many problems, its contribution is immeasurable, it can enable the earth to gently obtain the sun's energy, and it can also make the atmosphere have enough condensation nuclei to increase the chance of cloud and rain formation; Regulate the temperature of the earth's surface to make it suitable for the survival and reproduction of life.

Dust is very harmful to the computer, too much dust may block the CPU fan, make the fan stop, cause the CPU to overheat and burn the consequences, but also affect the contact between the boards, and may also cause corrosion of the circuit board.

Dust particles are typically 1 millimeter in diameter. to between a few hundredths of a millimeter. The dust that can be seen by the human eye is a behemoth in the dust, and the fine dust can only be seen under an electron microscope.

Above-ground dust is mainly industrial emissions, combustion dust, soil dust, etc. Dust absorbs some of the sun's rays while scattering light around. Like an infinite number of point light sources.

The light is scattered by the dust, and the intensity is greatly reduced, and it becomes softer. If there is no dust in the atmosphere, strong sunlight will make it impossible to open one's eyes. The gas of the gas is easy to make purple-blue, cyan three-color light.

So in general, the sky appears blue, and the dust is different, and he indiscriminately scatters seven colors of sunlight. We see that the distant sky gradually turns from blue to white as the altitude decreases, because the lower atmosphere has a higher level of dust. If there is no dust in the atmosphere, the entire sky will always be blue due to the scattering of sunlight by only gases.

Chan mostly has hygroscopic properties. The water vapor in the air must adhere to the dust in order to condense into small water droplets. In this way, when the water vapor in the air reaches saturation, the dispersed water vapor adheres to the dust and forms stable water droplets, which can float in the air for a long time.

If there were no dust in the air, everything on the ground would be wet. To make matters worse, it is difficult to form clouds and fog in the sky. It is difficult to form rain and snow to regulate the climate.

The water vapor evaporated from the ground into the atmosphere gradually increased. The relative humidity in the atmosphere is constantly rising. It will affect the survival of living things.

Also, due to the refractive effect of these small water droplets on sunlight. There will be sunset. Idle clouds and mist, rainbow and sunburst halos and other natural scenery with thousands of meteorological conditions.

If there were no dust in the air, how monotonous nature would be!

What would the world be like without dust? When people think of dust, they immediately think of dirt and unhealth. So everybody wonders if there was no dust in this world!

In fact, if human beings really leave the dust one day, the consequences will be unimaginable. If there were no dust, there would be no clouds of different shapes, soft and cool shades, and shadows of various postures. Without the dust, we don't enjoy the colorful smoke that envelops the peaks and the breathtaking sunset.

It is because of the tiny dust particles suspended in the atmosphere, which, together with the air molecules, intercept and scatter the shortest (blue) light waves of the sun's rays, that we have magnificent blue skies. When the sun goes down, the dusty atmosphere reveals longer waves of orange and red light, decorating the sky with splendor. In addition to providing visual beauty, dust also offers many tangible benefits to humans.

Yeast is produced by spores, and this "chemist" in the "kingdom" of dust can break down sugar into alcohol and carbon dioxide, and make wine from grape juice and barley into beer, respectively. Another example is the pollen in the dust, which swims everywhere, allowing most plants to multiply and "pass on from generation to generation". Where does the dust come from?

In fact, most of them are produced by human beings, and one-third of them are produced by factories and enterprises, especially steelmaking, quarrying, cement manufacturing and flour processing enterprises. Fifty-five percent of man-made dust is caused by the combustion of various fuels. One of the most important ** of natural dust is, of course, dirt, and its other "donor" is the ocean.

Every time the waves are broken, the winds carry countless particles of salt to islands or land, hundreds of kilometers away. The total weight of these crystalline particles transported by the ocean is 300 million tonnes per year, which is one and a half times more than the annual production of salt mined by humans. In addition, volcanic ash can circle the earth several times, adding to the dust "ranks".

There is also a ubiquitous type of dust that comes from outer space. Scientists speculate that over the past billion years, this cosmic dust, mainly from meteors burning in the atmosphere, has fallen an inch thick on Earth. Some of the dust came from the moon, which was the result of a large meteor colliding with the surface of the moon.

Some of the dust is Martian and an asteroid has collided with it.

The vast majority of people who have cleaned their houses will feel that the less dust they have, the happier they will be.

However, if there is no dust, the rainfall will be less and the afterglow of the sunset will not be colorful. Rain is formed due to the accumulation of water molecules in the air around the dust. When the water vapor condenses to a certain extent, it forms small water droplets, which are heavy enough to cause it to fall to the ground, that is, rain.

Therefore, in the absence of dust particles, water vapour is unlikely to form rain.

Water vapor and dust particles also reflect sunlight. At sunrise and sunset, when the sun is still below the horizon, dust and water vapor molecules reflect longer wavelengths of red light, allowing us to see the sun for a longer period of time (earlier at sunrise and longer at sunset). The more dust particles there are in the atmosphere, the more colorful the sunrise or sunset will be.

Without dust, sunlight is not absorbed, reflected, scattered, and refracted, and the sky is either too bright or too dark. Dust is so important to our world that without it, we wouldn't even be able to see a beautiful sunset.

Without dust, sunlight cannot be absorbed, reflected, scattered and refracted.

And the water vapor in the air cannot be condensed, it is difficult to form clouds, the surface is not covered by clouds, it will be arid and barren, and the weather is either too hot or too cold.

Harmful rays from the universe can break into the earth's surface and pose a threat to humans and various living things.

Without dust, the immune system of man and all living things will collapse, and without an immune system you can imagine that it will not be long before animals will perish, and people may have to be kept in greenhouses.

If there were no dust in the atmosphere, the sky would be white. If the dust in the atmosphere. The sky will be scorching hot. If there is no dust in the atmosphere, the ground will be wet.

Then there will be no human beings, and we will die quickly!!

1. There will be no clouds in the sky, there will be no rain, water will no longer circulate, and living things may no longer exist;

2. Without dust absorbing moisture, the whole world will be wet;

3. Sunlight will become very dazzling without the diffuse reflection of dust;

The earth will not rain or not!!

Xiao Jun |Level 1: There will be no clouds in the sky, there will be no rain, water will no longer circulate, and living things may no longer exist;

2. Without dust absorbing moisture, the whole world will be wet;

1.It won't rain.

2.It won't snow.

3.Soggy.

4.The sun is blinding.

4.The sun is blinding.

5.There is no morning glow. Rainbow. Clouds.

It will not rain on Earth!! Because the water vapor has to be condensed together through the dust to form rain!! Very serious!! It doesn't rain, it doesn't snow, the wet sun is dazzling, and there is no morning glow. Rainbow. Clouds.
