If we ignore all ifs & buts, then the exact temperature for melting of snow/ice is 0.01 degree C or 32.02 degree F. While answering this, we should also remember that water has a triple point at this temperature, i.e., it can exist in all the three forms - solid, liquid and gas.

Microorganisms can be found virtually in every part of Earth from deep sea vents, hot springs, deep buried rocks to high up in the atmosphere.ome scientists also classify viruses as microorganisms.
