I think that the dust is the product of desintegration of rocks due to some kind of erosion of wind, water, or land along with the temperature changes, or chemical reaction. May be due to the radioactive decay of minerals that desintegrate the rocks into the dust.
So, Venus has "no water", on the surface has very low wind speed and very low temperature changes (I doubt it, since Venus has night that I don't know how much is the temperature drop between the day (470 Centigrade) and night ??. The rest venusian dust might be due to the chemical reaction or radioactive decay of some rocks? Rodolfo |

I'm curious -- if you don't know how much the temperature drop is between night and day on Venus, but you are interested enough to discuss the matter, why don't you look it up on the Internet before posting? It seems odd to me that a poster perceiving himself to lack information would have a greater motivation to analyze a phenomenon (and post the un-informed analysis) than to get basic information about the phenomenon. The information is not hard to come by, and un-informed analysis is all too easy to come by! Put another way: If you have ten units of personal energy, which do you think helps the board more: five researched topics and five informed posts, or ten uninformed posts? |
