HYDROLOGICAL CYCLE
The hydrological cycle is a basic process of material cycling that is crucial to all life on earth. Precipitation waters crops for us to eat, replenishes streams, lakes, and wetland habitats, supported the growth of forests, and recharges the groundwater supplies that provide the water we drink.  Evaporation withdrawals water from earth and stores it in the atmosphere as clouds, until weather conditions stimulate a rain shower.
