Dust question.... does anyone know the answer?

Question

Where does dust come from?

Answer 1

Dust is in the air.  It is a very small partical which floats around us everyday.  Normally you can not see it unless you have a beam of sunlight coming throught the room, then you will see a lot of particals floating around in the air.  Dust is made of a lot of different items such as bits of dirt, pollution from factories and car/trucks which the wind blows around and finally settles down on something which we call dust.  As is accumulate you can see it more and it shows on a dark surface more than a light surface.  Hope this helps.

dust is the huge part of our earth...actually its not dust..its the mud particles and on Earth, dust occurs in the atmosphere from various sources; soil dust lifted up by wind, volcanic eruptions, and pollution are some examples. Airborne dust is considered an aerosol and can have a strong local radiative forcing on the atmosphere and significant effects on climate....Dust samples returned from outer space could provide information about conditions in the early solar system. Several spacecraft have been launched in an attempt to gather samples of dust and other materials.
