Importance of dust
- Is dust also useful. People's perception about dust is that it is useless. It doesn't work any of us, but it's not really. Dust is also very useful for us. Before talking about the use of dust, it is important to know what the dust is and how it is produced.
- Each solid material consists of very fine particles. When these tiny particles of matter are dispersed, they become dusty. For example, if we go on breaking a brick or a stone, it will form small particles. These particles are called dust when they fly in the air. Dust particles fly from one place to another due to wind. There are many reasons for dust formation. Dust is produced when solid objects break down. The smoke emanating from the burning of coal, wood, petrol, etc., and the lava emanating from the mouth of the volcano also lead to dust.
- The largest use of dust particles is related to rainfall. The water vapour in the clouds is able to form droplets only because of dust particles. Water vapour accumulates in the form of water on dust particles and gives life to our earth in the form of rain. If there are no dust particles, it is very difficult to make droplets from the water vapour. Similarly, mist, fog, etc., are caused by dust particles. The dust particles present in our atmosphere reflect the rays of the sun around. One advantage of this is that even after the sun is hidden, it is not dark for a couple of hours. The red appearance of the sun at sunrise and sunset is also due to dust particles and vapours. The beautiful rays of the sun that are visible in the Twilight are also visible due to dust particles. Thus we see that the dust particles that we consider useless are also very useful to us.
