Water Cycle
Water is really a very powerful factor of all ecosystem . All organisms need water for their survival and growth . Water has three phases - solid , liquid and gas . The liquid phase is important for living a life on planet and gaseous phase is important for the respiration process . Water cycle is also known by its another name" Hydrological Cycle ".
Water Cycle - Water cycle is generally the journey of water from one place to another and from one state to another state . Their is no end and it is a continuous process that is why it is called "Cycle" . Let us understand the water cycle
The sun heats the surface of earth as a result the water starts evaporating in the form of water vapor . The water vapor condense and change into liquid and form clouds this process is called as condensation . The water now fall from the clouds in the form of precipitation ( rain, snow ) and collected into the water reservoir like see , ponds . lakes , river . Some of the water is absorbed into the earth surface as a ground water and use by plants and animal for drinking purpose or it may be run off from the soil and collected into the ocean , river and lakes from where again cycle starts.
