the temperature is below freezing & the freezing point of water is 32f / 0c / 273k & freezing is usually used to refer the freezing point of water in real life ->  the temperature is below 0 c  the temperature is below 0 c & precipitation is when water falls from the sky & water is in the solid state , called ice , for temperatures between 0 / -459 / -273 and 273 / 32 / 0 k / f / c ->  the precipitation of water will be in ice form when temperature is below 0 c  snow is a kind of ice & snow is a kind of precipitation ->  snow is precipitation in ice form  the precipitation of water will be in ice form when temperature is below 0 c & snow is precipitation in ice form -> the precipitation will be in snow form when the temperature is below 0c
