on Venus snow means metal particles

It snow's on Venus, but metal snow..!!!
As we know Venus is the hottest planet in the solar system where the average temperature of the surface is about 472 °C. This temperature is much enough to melt and vaporize metal like lead and bismuth and rise above into the atmosphere of Venus.
But the temperature above in the atmosphere of Venus is very low as compared to the surface i.e. ranges from -43 °C to -173 °C. 
As we go away from the surface the temperature decreases.
So as the metal vaporizes and goes above in the atmosphere of Venus it condenses and gets back to the surface in the form of snow, which then covers the very top of the mountains present on Venus which looks like snow.. but it's metal particles.

There is a small story behind this. The great lord buddha who started the very oldest and very famous religion, "BUDDHISM '', was once meditating under a tree. It was a sunny day, and Buddha was deeply engrossed in his meditation. But as time passed, the temperature also increased, and soon the sun lined up on buddha's head.
