what is rain ?


assistant
Water from various water bodies like lakes, oceans along with water from plants & trees evaporate as vapour due to the heat from sun. This rises, cools and changes into tiny droplets of water which form clouds. Multiple tiny droplets join to form bigger water drops and once they become heavy enough, they come down as rain. Small droplets are called drizzles and the bigger ones as rain !
