Why do we have rain?

                                        Why do we have rain? Because of sun's heat, the water is evaporated into air as vapors and currents takes water vapors up in atmosphere.
As these vapors rises in air, cooler temperatures cause it to condense into clouds.
Air currents move clouds around the globe, cloud particles collide, grow, and fall out of the sky as rain and snow.
This is how we get our rains.
