Select all that apply.

a sufficient decrease in relative humidity

a sufficient decrease in temperature

a sufficient increase in temperature

a sufficient increase in relative humidity

Solution

Answer is- sufficient decrease in temperature.

It is the temperature that plays all the role in formation and precipitaion of water vapours. When temperature is high, water evaporates, as temperature rises the kinetic energy of water molecules also rises making them move apart from each other and turning into vapour which is invisible. As temperature starts falling, the kinetic energy lowers down and water molecules start coming close to each other. Further decrease in temperature makes water fall back to the earth\'s surface in the form of rain.
