#Mathematical walk in nature, http://amzn.to/gDp75C Q42: How much average cloud weight? values: length = 1 km = 1x10^3 m- we measure length of cloud using cloud shadow, volume = 1 km^3 = 1 m^9 - our cloud is perfect cloud density = 0.5 g/m^3 = 0.5x10^-3 kg/m^3= 5x10^-4 kg/m^3 calculation:

500000 kg =  500 tons

500000 kg =  500 tons

#using wolframalpha, we can compare it: #query: http://www.wolframalpha.com/input/?i=compare+500+metric+tons ~ 6 × large dinosaur mass (~ 90000 kg ) ~ 1/4 of space shuttle launch mass
