Found mostly in oceans and other large bodies of water, with 1.6% of water below ground in aquifers and 0.001% in the air and vapor, (suspended particles formed of solid and liquid water in the air) clouds, oceans Alomtar.akd 97 % of surface water, glaciers and polar ice caps 2.4%, and other land surface water such as lakes, rivers and ponds 0.6%. Full very small amount of water in the ground within biological bodies and manufactured products.
Water is considered a renewable source of water where the constantly moving through the water cycle caused by evaporation or transpiration by the sun, which in turn works on the condensation of the clouds to generate rain beads, then go down to liquid form rather than gaseous, as well as when it is can be downloaded on the solid form (cold) or (snow) depending on the temperature of the area where the generated rain beads.
water resources :
