It is the science which deals with occurrence ,movement and distribution of water upon ,over and beneath the earth surface .It is in the form of cycle and known as hydrological cycle
WHAT IS HYDROLOGY?

PRECIPITATIONIt is the fall of water in various forms on the earth from the atmosphere. It is in the form of rain , snow, hail, and dew
Air contains gases/such as Nitrogen,Hydrigen,Oxygen ,Co2, and Water vapors
