Firstl,the hot sun helps water in the lakes and oceans to evaporate.This turns the liquid water into a gas called water vapour,which goes up into the air.Then this water vapour in the air will cool off when it rises up into the sky,and turn back into water droplets.Next,when enough of these water droplets have condensed in the air,we can see the water as a cloud .The cloud may be blown by the wind.Sooner or later it will rise again,and the air around it will be even cooler.Finally,after a while,the cool air can't hold the water droplets up any more,and they fall to the ground as rain.
