There is speculation that with time the atmosphere of the Earth kept on altering for millions of years and an intensive water vapor ruled over the atmosphere for considerable duration and contributed towards shaping the present Earth’s atmosphere. Evaporation from water bodies both from the Oceanic regions and inland water bodies also played crucial for atmospheric changes. Organisms, whether belonging to flora and fauna also had some roles through transpiration or other biological processes. Over millions of years, a certain balance has stabilized water circulation between the atmosphere and the planet's surface. Precipitation for a specific geographical region with specified volume altogether may impact the present situation. Small atmospheric changes collectively impact the overall climate which requires ample time.
