If there is no dust in the atmosphere, the light directly from the sun on the earth will not be absorbed, reflected, scattered and refracted, and the sky will be very blue, without snow, rain and dew, sunshine and rainbow. Because dust is a hygroscopic particle, without its core, water vapor in the air will not condense, and it is difficult to form clouds in the sky. Without the cover of clouds, the surface will become dry and barren, and the weather will be either too hot or too cold. Without dust, many harmful rays in the universe will break into the earth's surface without hindrance, posing a fatal threat to human beings and all kinds of creatures.
In addition to these benefits, dust can condense water vapor. Let them become water drops, otherwise, everything will be wet and living things can't survive.
Although Dust has many shortcomings, its contribution is endless. It can make the earth get solar energy gently, and it can also make enough condensation nuclei in the atmosphere, increasing the chances of cloud and rain formation. Adjust the surface temperature to make it suitable for the survival and reproduction of life.
