WHAT WOULD HAPPEN IF THERE WERE NO
DUST?
Would the world really be so much better off if there were no dust? The answer is in some ways in the affirmative but in some ways in negative. The ensuing paragraphs clarify the usefulness of Dust.
What is dust , anyway ? It consists of
particles of earth, or other solid matter , which are light enough to be raised and carried by the wind . Where do these particles come from? They might come from dead plants and animal matter , from sea salt ,from desert or volcanic sand , and from ashes or soot. In the modern world the exhausts from Industries and Automobiles are also big creators of Dust.
For the most part, dust is not a very desirable or beneficial thing .But in one way it helps make the world more beautiful ! The lovely colors of the dawn and of twilight depend to great extent on the amount of dust that is present in the
air .
Particles of dust in the upper air reflect the Sun
rays. This makes its light visible on earth an hour or two after sunset. The different angles as they are reflected by dust and water
vapor particles. Sunsets are red because these particles bend the red rays of the sun in such way that they are the last rays to disappear from view.
Another useful function of dust has to do with rain .The water vapor in the air would not become a liquid very readily if it did not have the dust particles serving as centers for each drop of water. Therefore, clouds, ,mist, fog and rain are largely formed of an infinite number of moisture laden particles of dust .
There is already more than adequate amount of Dust in the Earth’s atmosphere. Therefore for its beneficial aspects one need not have to create it but minimize it to a large extent. On the earth Dust generation never stops and is a continuos natural phenomenon.
