It is known that about 25 to 50 per cent of average rainfall flows away on the surface of the ground. A large portion of surface water evaporates and the remaining part goes underground. Inland water changes its flow according to flow routes as per geological structure of the relevant area. Some rocks are aquifers, others are aquiclude.
Water Resources
Flow of water inside the ground is affected by structure and composition of the soil. Thus, even inside the earth, the process of hydrological cycle is performed. It is not necessary that all the ideal conditions of water cycle may be completed in the same sequence, because many factors affect this geographical process:.
Man has artificially changed the atmospheric composition and thereby affected the water cycle. As a result of such change, there can be change in movement of evaporation from ground as well as oceans and its direct effect is on quantity of rainfall. Quantity of air particles is changing because granules emitted by industries work as humidity centers for formation of drops of rain. Thus, solid particles in atmosphere, effect of pollution and formation of clouds affect the quantity and image of rainfall.

Man affects the water cycle by impacting on surface flow of water in many ways. Due to the economic race, man has done mining by unscientific methods, and thereby disturbed the balance of nature and the functioning of the hydro- logical cycle. Hydrological cycle is important on the earth for various organic activities because hydrological balance would be disturbed without water communication and any type of life would become impossible.
Evaporation of water and its storage in atmosphere is a very important process.

Seasonal variations depend on it. Performance of rainfall on the earth is completed only by the hydrological cycle. Biogeochemical cycle is completed on the earth with water cycle.
Among different biogeochemical cycles on the earth, vegetation is an effective medium for movement of sediments and chemical substances. Thus, biogeochemical cycles on the earth are possible only through movement of water. In nature, universal hydrological cycle is a closed ecological system because hydrological cycle on the earth does not exchange energy in the universe, it only gets energy.
Pure water is tasteless, odorless, and colorless. Water can occur in three states: solid (ice), liquid, or gas (vapor). Solid water—ice is frozen water. When water. The forms of water. Drinking a glass of water is the most simplest act in the world. Or rather, in this world. Very special and very rare conditions.
On the earth, it does not get humidity from outside, and the companion water in hydrological cycle is stable. It does not increase or decrease.

There is only seasonal variation but on the world level there is no change in its quantity. Total evaporation from oceans is 86 per cent and 14 per cent from ground level whereas, rainfall is 79 per cent on oceans and 21 per cent on the ground level. This additional 7 per cent moisture moves from seas towards the ground through clouds and again transfer of water from ground towards seas through rivers and groundwater maintains the balance.

Researchers have known for a long time that ice can exist in two forms -- an ordered, crystalline phase and an amorphous, or disordered phase -- and that there are two forms of amorphous ice with low and high density. In this study, the researchers investigated whether liquid water can also have low- and high-density forms. The results are based on experimental studies using X-rays, which were published in the journal Proceedings of the National Academy of Science.
These new results not only create an overall understanding of water at different temperatures and pressures, but also how water is affected by salts and biomolecules important for life. The researchers believe that the increased understanding of water can lead to new insights on how to purify and desalinate water in the future. Water has many strange or anomalous properties and behaves very differently from all other liquids. Some examples are the melting point, the density, the heat capacity, and all-in-all there are more than 70 properties of water that differ from most liquids.
These anomalous properties of water are a prerequisite for life as we know it. This story has not been edited by economictimes. Read more on London. Stockholm University.
